The steel materials shall be melt processed either by electric process or oxygen blown process. The steel shall be fully killed and shall conform to the required austenitic grain size. Product analysis shall be performed on and the steel specimens shall conform to the required chemical compositions of nickel, chromium, molybdenum, phosphorus and sulfur. Proof tests shall be performed and the materials shall conform to the required values of working load and breaking force. Deformation test, breaking force test and fatigue test shall be performed on the steel materials.
SCOPE
1.1 This specification covers the requirements for forged alloy steel lifting components and welded coupling and master links for Grade 80 and Grade 100 alloy chain slings as described in Specification A906/A906M.  
1.2 Two grades of components and welded links are covered:

ABSTRACT
This specification covers carbon steel chain for such applications as railroad cars, construction, industrial uses, load binding, and general purposes other than overhead lifting. The three classes of carbon steel chains covered here include Grade 30 (proof coil chain), Grade 43 (high test chain), and Grade 70 (transport chain). The dimensional requirements of the chain with respect to the appropriate grade and size are presented. The mechanical testing requirements for the steel includes, proof testing, breaking force testing, and elongation testing. One test for breaking strength and elongation shall be made from each lot. The elongation and breaking force tests may be performed at the same time on the same test specimen.
SCOPE
1.1 This specification covers carbon steel chain for such applications as railroad cars, construction, industrial uses, load binding, and general purposes other than overhead lifting.  
Note 1: This specification does not cover carbon steel chain for sprocket applications.  
1.2 Three classes of carbon steel chain are covered:  
1.2.1 Grade 30—Proof coil chain.  
1.2.2 Grade 43—High test chain.  
1.2.3 Grade 70—Transport chain.  
1.3 The chain grade is based on the nominal stress in the link at the design breaking force strength. It is calculated by taking the minimum breaking force load and dividing by two times the nominal cross-sectional area of the link.  
1.4 The values stated in either SI units or in other units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4.1 Metric Units—Grade = 1/10 of the minimum breaking force in kilonewtons divided by two times the nominal cross-sectional area in square millimeters. = (MBF)/(0.005)(π)(d)(d)  
1.4.2 English Units—Grade = 0.000689 of the minimum breaking force in pounds divided by two times the nominal cross-sectional area in square inches. = (0.000689)(MBF)/(0.5)(π)(d)(d)  
1.4.3 MBF = minimum breaking force (lb or kN); d = chain diameter (in. or mm).
Note 2: The above formulas are for round diameter links only. If different cross sections are used, the actual cross section of the link would need to be calculated and used.  
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.

The alloy steel chain shall be made to a fully-killed fine austenitic grain process. Alloy steel chain may be made by the electric welding or gas welding process. The material shall be heat treated which includes quenching and tempering. Material's composition shall conform to the chemical requirements for carbon, phosphorous, sulfur, nickel, chromium, and molybdenum. The material shall conform to the mechanical property requirements for breaking force and elongation and to the dimensional requirements for the appropriate size chain. All chain shall be tested to at least the proof load.
SCOPE
1.1 This specification covers Grade 80 heat-treated alloy steel chain for such applications as slings, lifting assemblies, and load binding.
Note 1—This specification does not cover alloy steel chain for pocket wheel applications.  
1.2 The Grade designation is 1/10 of the minimum breaking strength in newtons divided by two times the nominal cross-sectional area of the chain in square millimetres.
1.3 The values stated in either SI units or in other units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.

SCOPE
1.1 This specification covers welded carbon steel machine chain and coil chain. Although these chains are not intended for pocket wheel use, they can be used for pocket and sprocket wheel use. This chain shall never be used for overhead lifting applications.
1.2 There are two classes each of machine and coil chain:
1.2.1 Class MS—Machine, straight-link steel chain,
1.2.2 Class MT—Machine, twist-link steel chain,
1.2.3 Class CS—Coil, straight-link chain, and
1.2.4 Class CT—Coil, twist-link steel chain.
1.3 The values stated in either inch-pound units or SI units shall be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.

ABSTRACT
This specification covers forged alloy steel lifting components and welded coupling and master links for Grade 80 and Grade 100 alloy chain slings. The steel materials shall be melt processed either by electric process or oxygen blown process. The steel shall be fully killed and shall conform to the required austenitic grain size. Product analysis shall be performed on and the steel specimens shall conform to the required chemical compositions of nickel, chromium, molybdenum, phosphorus and sulfur. Proof tests shall be performed and the materials shall conform to the required values of working load and breaking force. Deformation test, breaking force test and fatigue test shall be performed on the steel materials.
SCOPE
1.1 This specification covers the requirements for forged alloy steel lifting components and welded coupling and master links for Grade 80 and Grade 100 alloy chain slings as described in Specification A 906/A 906M.
1.2 Two grades of components and welded links are covered:
1.2.1 Grade 80.
1.2.2 Grade 100.
1.3 This specification is a performance standard. Other standards apply to use of these products. Some of these standards are: OSHA 1910.184, ASME B30.10, and ASME B30.9.
1.4 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

ABSTRACT
This specification covers requirements and method of rating and testing for alloy chain slings. Only component parts compatible with alloy chain shall be used. Sling assembled by welding shall be fabricated by the electric or gas welding process, or both. The material shall undergo proof test to meet the prescribed mechanical requirements. Several grades of alloy chain sling shall conform to the specified working load limit values.
SCOPE
1.1 This specification covers the requirements and method of rating and testing for alloy chain slings. Slings shall be assembled using components manufactured in accordance with Specification A 391/A 391M for Grade 80 chain, A 973/A 973M for Grade 100 chain, and A 952/A 952M for other components.
