Common stainless steel bar specifications

ASTM A276: This specification covers hot or cold finished bar except bars for reforging (see spec. A314). Includes rounds, squares, hexagons, hot rolled or extruded shapes such as angles, flats, channels and commonly used grades of stainless steel, including ‘improved machinability’. Free machining grades such as 303 and 416 are not included (see spec. A582/A582M).
ASTM A479M: This specification covers the same sections as ASTM A276, for use in pressure vessel construction. Also referred to in ASME boiler and pressure vessel code.
ASTM A582M: This specification covers hot or cold finished free-machining stainless steel bar except bars for forging (see spec. A314). Includes rounds, squares and hexagons in the more commonly used types of stainless steels designed for optimum machinability and general corrosion and high temperature service, primarily grades 303 and 416. Stainless steel bars other than the free-machining types are covered in other specifications.
ASTM A314: This specification covers stainless steel billets and bars intended only for forging.
ASTM A484M: This specification covers general requirements that apply to stainless steel wrought bars, shapes, forgings and billets or other semi-finished material (except wire) for forging, under the latest revision of each ASTM specification.

Note: Grades 431 and 2205 are often stocked in a smooth turned or centreless ground finish.

Stainless steel bars comprises numerous products referred to by the shape, the section dimension, grade, condition and surface finish.

Shapes and section measurement

Round bar: measured across the diameter.
Square bar: measured across the flats (AF).
Hexagonal bar: measured across the flats (AF)
Flat bar: measured width x thickness
Equal angle: measured length x width of external faces
x material thickness.
Channels: measured flange x web x thickness.
Hollow bar: measured outside diameter (OD) x inside diameter (ID)
