Standard Specification for Alloy Structural Steel Plates

ABSTRACT
This specification deals with alloy structural steel plates. Plate specimens addressed under this specification are available in four treatment conditions (as rolled or hot rolled; annealed; normalized; and normalized and tempered), three structural forms (rectangular; circular and semi-circular; and sketch, including rings), five edge categories (mill edge; universal mill edge; sheared edge; gas cut edge; and special cut edge), and seven finishes (as rolled or hot rolled; blast cleaned; blast cleaned and oiled; pickled; pickled and oiled; painted with one prime coat; and painted with one prime coat and one finish coat). Steel materials shall be manufactured and furnished in defined procedures unless specified otherwise in the purchase order. Heat analysis shall be performed wherein steel specimens shall conform to required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, vanadium, and copper. Specimens shall also undergo tensile tests and shall conform to required values of tensile strength.
SCOPE
1.1 This specification covers structural quality alloy steel plates.

1.6.8 The plates are usually specified to have Finish 1.  
1.7 Supplementary requirements are provided for additional requirements that may be specified on the order.  
1.8 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.  
1.9 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.

Overview

ASTM A829/A829M-17 is the standard specification developed by ASTM International for alloy structural steel plates used in construction, heavy machinery, transportation equipment, and various industrial applications. This standard outlines the requirements for chemical composition, mechanical properties, manufacturing methods, and delivery conditions to ensure the consistent quality and performance of alloy steel plates. The document is recognized internationally and supports compliance with global trade and engineering practices.

  • Rectangular
  • Circular and semi-circular
  • Sketch (including rings)

Edge and Finish Options

• Five edge categories:
  • Mill edge
  • Universal mill edge
  • Sheared edge
  • Gas cut edge

Chemical Composition and Mechanical Properties

• The standard specifies the chemical composition requirements for key alloying elements including carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, vanadium, and copper.
• Plates may also be ordered to meet specific tensile requirements compatible with their composition, treatment, and thickness.

Testing and Certification

• Requirements for heat analysis and mechanical testing to verify compliance with specified grades.
• Certification of composition and mechanical test results must be provided to purchasers.

Supplementary Requirements

• Purchasers may specify additional requirements such as vacuum treatment, product analysis, and ultrasonic examination as needed for critical applications.

Applications

Structural alloy steel plates conforming to ASTM A829/A829M-17 are widely used in:

• Bridge and building construction: Supports load-bearing frameworks requiring high strength and toughness.
• Industrial equipment manufacturing: Machinery parts, gears, and heavy-duty components.
• Rolling stock and shipbuilding: Chassis, frames, and structural assemblies exposed to dynamic loads.
• Pressure vessels and tanks: Plates are selected for their mechanical reliability under varying stress conditions.
• Transport infrastructure: Suitable for automotive, rail, and heavy transport vehicle frames.

The wide range of available conditions, surface finishes, and edge treatments allow engineers to choose plates tailored to specific project requirements, ensuring optimal performance, durability, and fabrication compatibility.

Related Standards

Plates supplied under ASTM A829/A829M-17 must also comply with general delivery and testing requirements outlined in:

• ASTM A6/A6M: General Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling

For welding and fabrication guidance, consult:

• Specification A6/A6M Appendix X3: Information on weldability and recommended welding procedures for various steel grades

Other relevant standards may include those specifying requirements for structural steel applications in specific industries, such as bridge construction (ASTM A709), pressure vessel plates (ASTM A537), and requirements for testing methods.
