This specification covers alloy steels having a chromium content equal to or less than 11.0% in plate, sheet, strip form for corrosion, and heat-resisting applications. Some steels, especially the high silicon containing steels, because of their particular alloy content and specialized properties, may require special care in their fabrication and welding. The steel shall conform to the requirements as to chemical composition. The mechanical properties such as tensile strength, yield strength, elongation and hardness shall be determined.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers alloy steels having a chromium content equal to or less than 11.0 % in plate, sheet, strip form for corrosion, and heat-resisting applications.

1.2 Some steels covered by this specification, especially the high silicon containing steels, because of their particular alloy content and specialized properties, may require special care in their fabrication and welding. Specific procedures are of fundamental importance, and it is presupposed that all parameters will be in accordance with approved methods capable of producing the desired properties in the finished fabrication.

1.3 The values stated in inch-pound units or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.4 This specification and the applicable material specifications are expressed in both inch-pound and SI units. However, unless the order specifies the applicable "M" specification designation (SI units), the material shall be furnished in inch-pound units.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
