The ASTM A479 specification covers hot-rolled and cold-rolled stainless steel bar, including round, square, and hexagonal, as well as hot-rolled or extruded shapes for boiler and pressure vessel construction, such as angles, tees, and channels. Four grades of stainless steel are available, including austenitic, austenitic-ferritic, ferritic and martensitic grades. Mechanical properties, such as tensile strength, yield strength, elongation, and hardness, shall be determined for specimens subjected to normalized, tempered, annealed, and quenched conditions.
