1.1 This specification covers hot- and cold-finished alloy steel bars having a chromium content equal to or less than 11.0 % including rounds, squares, hexagons, and hot-rolled or extruded shapes for use in corrosion and heat-resisting service.

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 test methods capable of producing the desired properties in the finished fabrication.

1.3 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.

1.4 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.


This specification covers hot- and cold-finished alloy steel bars including rounds, squares, hexagons, and hot-rolled or extruded shapes for use in corrosion and heat-resisting service. The steel specimens shall be furnished in the solution annealed condition with subsequent light drawing and straightening permitted. The steel materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, and molybdenum. Mechanical tests shall be performed wherein the materials shall conform to the required values of tensile strength, yield strength, elongation, and hardness.
