ASTM A484 Specifications

ASTM A484 / A484M - 16 Standard Specification for General Requirements for Stainless Steel Bars, Billets, and Forgings. - ASTM A484 Specification includes wrought stainless steel bars, shapes, forgings, and billets or other semi-finished materials, except wire, for forging. The ASTM A484 bars shall be furnished in one of the following conditions:

hot-worked
hot-worked and annealed
hot-worked, annealed and cold-worked
hot-worked, annealed, and heat-treated.

The materials are heat treated; austenitic stainless steels and austenitic-ferritic grades are produced in a solution annealed condition, ensuring conformity to the required specifications for temperature, permitted annealing procedure, quenching, and rapid cooling.

S41000	410	5613	A-276 A-314 A-479 A-493	QQ-S-763	410 is a low cost general purpose stainless steel, that hardens at 35-39 RC and is used widely where corrosion is not severe.
S42000	420	5621	A-276 A-314	QQ-S-763	420 is similar to 400, but the raised carbon content produces higher strength and hardness. Heat treatment to 50 RC min.
