"Standard Specification for Stainless Steel Bars and Shapes" hot-finished or cold-finished bars except bars for reforging. It includes 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. The free-machining types for general corrosion resistance and high-temperature service are covered in a separate specification. | Designation A276 A276M 16a Standard Specification for Stainless Steel Bars and Shapes1 This standard is issued under the fixed designation A276 A276M the number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision.
