Historical (view previous versions of standard)
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.
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.
1.1 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
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.
