Standard Specification for Nonoriented Electrical Steel, Semiprocessed Types

Standard Specification for Nonoriented Electrical Steel, Semiprocessed Types

ABSTRACT
This specification covers the standard requirements for flat-rolled, nonoriented semiprocessed electrical steel intended primarily for commercial power frequency applications in magnetic devices. These electrical steels are low carbon, silicon-iron, or silicon-aluminum-iron alloys, and are classified according to core-loss. Unlike the fully processed electrical steels covered by ASTM A 677, the electrical steels in this specification require heat treatment by the user to develop the specified magnetic properties. The steels covered by this specification have a thickness of either 0.0185 in. (0.47 mm) or 0.025 in. (0.64 mm). For each thickness there are four core loss types. The core loss shall be determined following the use of a quality evaluation anneal listed in the specification. The core loss is determined using the Epstein test method at a test frequency of 60 Hz and a maximum flux density of 15 kG (1.5 T). Test methods to determine other required physical and mechanical properties are listed. Other typical magnetic and physical properties are listed for reference.
SCOPE
1.1 This specification covers the detailed requirements to which flat-rolled, nonoriented semiprocessed electrical steel shall conform.
1.2 This steel is produced to specified maximum core-loss values and is intended primarily for commercial power frequency (50- and 60-Hz) applications in magnetic devices. Desirable core-loss and permeability characteristics are developed through heat treatment by the user.
1.3 These nonoriented, semiprocessed electrical steels are low carbon, silicon-iron or silicon-aluminum-iron alloys containing up to about 2.5 % silicon and less than 1 % aluminum.
1.4 The values stated in customary (cgs-emu and inch-pound) units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

ASTM A971/A971M-17(2022)(Test Method)
Standard Test Method for Measuring Edge Taper and Crown of Flat-Rolled Electrical Steel Coils

SIGNIFICANCE AND USE
5.1 Flat-rolled electrical steel master coils are usually slit into narrower coils. Usually these slit coils are punched or sheared into laminations of various shapes. The laminations are then uniformly stacked to become the cores of magnetic devices such as motors and transformers. Stacking of many laminations exhibiting excessive taper causes assembly problems and poor appearance. Nonuniform stack lengths in motors cause imbalance and noise. When the laminations are interleaved in transformers, taper causes air spaces within the core resulting in increased noise, increased exciting current, and higher core loss.
SCOPE
1.1 This test method provides a procedure for measuring edge taper and crown of flat-rolled electrical steel coils as produced at the steel mill.  
1.2 The values and equations stated in customary (cgs-emu and inch-pound) units or SI units are to be regarded separately as standard. Within this standard, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this standard.  
1.3 The following material specifications include requirements for edge taper or crown: A677, A683, A726, A876, and A1086. Specification A840 also includes requirements for edge taper or crown, but it has been withdrawn and reference to it is included for historical purposes.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Thin-Gauge Nonoriented Electrical Steel Fully Processed Types

SCOPE
1.1 This specification covers the detailed requirements to which flat-rolled thin-gauge nonoriented fully processed electrical steel shall conform. Nominal thicknesses included in this specification are 0.10 mm (0.004 in.) to 0.30 mm (0.012 in.).  
1.1.1 Refer to Specification A677 for properties of flat-rolled nonoriented fully processed electrical steel in nominal thicknesses of 0.36 mm (0.014 in.) to 0.64 mm (0.025 in.).  
1.1.2 Refer to Specification A876 for properties of flat-rolled grain-oriented fully processed electrical steel.  
1.1.3 Thin-gauge nonoriented electrical steels with a high silicon content (typically 61/2 %) manufactured using silicon vapor-deposition or similar processes are not included in this specification.  
1.2 The steel covered in this specification is produced to specified maximum core loss values and is intended primarily for use in rotating electrical machinery and other electromagnetic devices operating at moderate to elevated frequencies (100 Hz and greater). Desirable core loss and permeability characteristics are developed during mill processing; however, lamination manufacturing processes may adversely affect these mill-produced properties. Additional stress-relief heat treatment by the user may therefore be helpful in remediating these properties in the manufactured laminations. Stress-relief annealing is discussed further in Appendix X2.  
1.3 These thin-gauge nonoriented fully processed electrical steels are low-carbon, silicon-iron, or silicon-aluminum-iron alloys typically containing 2.5 to 3.5 % silicon and a small amount of aluminum.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard.  
1.4.1 There are selected values presented in two units, both of which are in acceptable SI units. These are differentiated by the word “or,” as in “g/cm3, or, (kg/m3).”  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Iron-Silicon Relay Steels

ABSTRACT
This specification covers wrought iron-silicon (Fe-Si) relay steels that are generally used in the manufacture of electromechanical devices, such as relays and solenoids, requiring higher electrical resistivity, higher permeability, and lower coercivity and residual magnetism than provided by either carbon steels or soft magnetic low-carbon irons. Available forms and conditions are forging billet, hot-rolled product, cold-finished bars, strip, and wire. These steels are not the same as the flat-rolled non-oriented or grain oriented iron-silicon electrical steels covered by ASTM Specifications A 677, A 683 and A 876. The steels covered in this specification have nominal silicon contents of 1.1, 2.3 and 4.0 % Si. Both the 1.1 and 2.3 % Si types are also available in an enhanced machinability composition. Along with chemical composition, steels produced to this specification must meet a specified maximum value of coercive field strength when heat treated according to this specification. Appendices are given containing typical magnetic, physical and mechanical properties and heat treatment.
SCOPE
1.1 This specification covers wrought iron-silicon (Fe-Si) steels that are generally used in the manufacture of electromechanical devices, such as relays and solenoids, requiring higher electrical resistivity, higher permeability, and lower coercivity and residual magnetism than provided by either carbon steels or soft magnetic low-carbon irons.

1.2 This specification covers steels in the form and condition required for fabrication into parts. The fabricated parts typically require a final heat treatment to obtain the desired magnetic performance. The term mill annealed as used in this specification applies to a heat treatment, typically applied by the producer, intended to improve formability. The mill anneal does not provide the optimum magnetic performance and is not intended to replace the need for the finish annealing of parts.  
1.3 This specification covers steels in the form of forging billets, hot-rolled bar and strip, cold-finished bar, wire, and cold-rolled strip in thicknesses up to 6.35 mm (0.250 in.).  
1.4 This specification does not cover electrical sheet steels used in transformer and motor laminations. Please refer to Specifications A677, A683, A726, A876, and A1086 for standards pertaining to these material types.  
1.5 This specification does not cover powder metallurgy materials capable of being processed into magnetic core components having similar silicon contents.  
1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard.

Standard Specification for Flat-Rolled, Grain-Oriented, Silicon-Iron, Electrical Steel, Fully Processed Types

ABSTRACT
This specification covers the detailed requirements for specified grades of flat-rolled, grain-oriented, fully processed low-carbon silicon-iron electrical steels, whose low core loss and high permeability in the direction of rolling have been achieved by appropriate metallurgical processing. These steels are primarily used in transformer cores operating at moderate to high magnetic flux densities at commercial power frequencies. These steels may be acquired in any of four conditions a.) conventional grain-oriented tested at 15 kG (1.5 T), b.) conventional grain-oriented tested at 17 kG (1.7 T), c.) high-permeability grain-oriented tested at 17 kG (1.7 T) and d.) laser-scribed high-permeability grain-oriented tested at 17 kG (1.7 T). These steels can be purchased in a number of combinations of material form and surface type or treatment. This specification explains in detail, the available forms, thicknesses and magnetic performance.
SCOPE
1.1 This specification covers the detailed requirements to which the specified grades of flat-rolled, grain-oriented, fully processed electrical steels shall conform. These steels are used primarily in transformer cores operating at moderate to high magnetic flux densities at commercial power frequencies (50 and 60 Hz).  
1.2 These grain-oriented electrical steels are low-carbon, silicon-iron alloys with a silicon content of approximately 3.2 % in which low core loss and high permeability in the direction of rolling have been achieved by appropriate metallurgical processing.  
1.3 The electrical-steel grades described in this specification include (1) conventional grain-oriented electrical steel tested at 1.5 T (15 kG) in accordance with Test Method A343/A343M, (2) conventional grain-oriented electrical steel tested at 1.7 T (17 kG) in accordance with Test Method A343/A343M, (3) high-permeability grain-oriented electrical steel tested at 1.7 T (17 kG) in accordance with Test Method A343/A343M, and (4) laser-scribed high-permeability grain-oriented electrical steel tested at 1.7 T (17 kG) in accordance with Test Methods A804/A804M.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM A677-16(Specification)
Standard Specification for Nonoriented Electrical Steel Fully Processed Types

ABSTRACT
This specification covers the standard requirements for flat-rolled nonoriented fully processed electrical steel intended primarily for commercial power frequency applications in magnetic devices. These electrical steels are low-carbon, silicon iron, or silicon-aluminum-iron alloys that may be made by basic-oxygen, electric-furnace, or other steelmaking practice. Desirable core-loss and permeability characteristics are developed during mill processing, so additional heat treatment is usually not required. The grades contained in this specification have thicknesses of 0.014 in. (0. 36 mm), 0.0185 in. (0.47 mm) and 0.0250 in. (0.64 mm). For a given thickness there are from 7 to 9 types based on the maximum value of core loss measured at 60 Hz and 15 kG (1.5 T) using the Epstein test method. Test methods to determine the required magnetic and mechanical properties are specified. Other typical magnetic and physical properties are listed for reference.
SCOPE
1.1 This specification covers the detailed requirements to which flat-rolled nonoriented fully processed electrical steel shall conform.  
1.2 This steel is produced to specified maximum core-loss values and is intended primarily for commercial power frequency (50 and 60 Hz) applications in magnetic devices. Desirable core-loss and permeability characteristics are developed during mill processing, so additional heat treatment by the user is usually not necessary.  
1.3 These nonoriented fully processed electrical steels are low-carbon, silicon-iron, or silicon-aluminum-iron alloys containing up to about 3.5 % silicon and a small amount of aluminum.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard.

Standard Specification for Nonoriented Electrical Steel, Semiprocessed Types

ABSTRACT
This specification covers the standard requirements for flat-rolled, nonoriented semiprocessed electrical steel intended primarily for commercial power frequency applications in magnetic devices. These electrical steels are low carbon, silicon-iron, or silicon-aluminum-iron alloys, and are classified according to core-loss. Unlike the fully processed electrical steels covered by ASTM A 677, the electrical steels in this specification require heat treatment by the user to develop the specified magnetic properties. The steels covered by this specification have a thickness of either 0.0185 in. (0.47 mm) or 0.025 in. (0.64 mm). For each thickness there are four core loss types. The core loss shall be determined following the use of a quality evaluation anneal listed in the specification. The core loss is determined using the Epstein test method at a test frequency of 60 Hz and a maximum flux density of 15 kG (1.5 T). Test methods to determine other required physical and mechanical properties are listed. Other typical magnetic and physical properties are listed for reference.
SCOPE
1.1 This specification covers the detailed requirements to which flat-rolled, nonoriented semiprocessed electrical steel shall conform.  
1.2 This steel is produced to specified maximum core-loss values and is intended primarily for commercial power frequency (50 and 60 Hz) applications in magnetic devices. Desirable core-loss and permeability characteristics are developed through heat treatment by the user.  
1.3 These nonoriented, semiprocessed electrical steels are low carbon, silicon-iron or silicon-aluminum-iron alloys containing up to about 2.5 % silicon and less than 1 % aluminum.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard.

ASTM
ASTM A1083/A1083M-23(Specification)
Standard Specification for Steel, Sheet, Cold-Rolled, Carbon, Structural, High-Strength Low-Alloy, Produced by Twin-Roll Casting Process

ABSTRACT
This specification covers cold-rolled, carbon, structural, and high-strength low-alloy, in coils and cut lengths produced by the twin-roll casting process. Cold-rolled steel sheet is available in the following designations: commercial steel, drawing steel, structural steel, and high-strength low-alloy steel. Sheet steel grades defined by this specification are suitable for welding if appropriate welding conditions are selected. For certain welding processes, if more restrictive composition limits are desirable, they shall be specified at the time of inquiry and confirmed at the time of ordering. The material shall be capable of being bent, at room temperature, in any direction through 180° flat on itself without cracking on the outside of the bent portion. Two tension tests shall be made from each heat or from each 50 tons [45,000 kg]. Yield strength shall be determined by either the 0.2 % offset method or the 0.5 % extension under load method unless otherwise specified.
SCOPE
1.1 This specification covers cold-rolled, carbon, structural, and high-strength low-alloy, in coils and cut lengths produced by the twin-roll casting process.  
1.2 Cold rolled steel sheet produced by the twin-roll casting process is available in the designations as listed in 4.1.  
1.3 This specification does not apply to steel strip as described in Specification A109/A109M.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
