1.1 This specification2 covers hot- and cold-finished bars of stainless steel, including rounds, squares, and hexagons, and hot-rolled or extruded shapes such as angles, tees, and channels for use in boiler and pressure vessel construction.2

Note 1: There are standards covering high nickel, chromium, austenitic corrosion, and heat-resisting alloy materials. These standards are under the jurisdiction of ASTM Subcommittee B02.07 and may be found in Annual Book of ASTM Standards, Vol 02.04.

1.2 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.

1.3 Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inch-pound units.

1.4 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.


This specification covers hot- and cold-finished bars of stainless steel, including rounds, squares, and hexagons, and hot-rolled or extruded shapes such as angles, tees, and channels for use in boiler and pressure vessel construction. Four grades of the stainless steel are available which includes austenitic, austenitic-ferritic, ferritic, and martensitic grades. Mechanical properties such as tensile strength, yield strength, elongation, and hardness shall be determined for the specimens subjected to normalized, tempered, annealed, and quenched conditions. The austenitic stainless steels shall be subjected to heat treatment and shall undergo corrosion test.
