Stainless Steel Bar Specifications
ASTM A276	This specification encompasses cold-finished or hot-finished bars, including rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels.
ASTM A479	This specification includes cold and hot finished stainless steel bars, including rounds, squares, and hexagons, and hot-rolled or extruded shapes such as angles, tees, and channels.
ASTM A484	This specification includes wrought stainless steel bars, shapes, forgings, and billets or other semi-finished materials, except wire, for forging. The materials are available in four types of conditions.
ASTM A582	This specification includes cold or hot finished bars, which are suitable for machining processes. This specification includes rounds, squares, and hexagons, from common types of stainless free-machining steels.
ASTM B473	This specification includes nickel alloy bar & wire, which can be produced in a solution-annealed condition, stabilized-annealed condition, or annealed condition.
