» ASTM A 276

Standard specification for stainless and heat resisting steel bars and shapes.

This specification covers hot finished or cold finished bars except bars for re-forging and hot rolled or extruded shapes, such as angles, tees and channels in the more commonly used type of stainless steel, excluding the free matching types of general corrosion resistance and high temperatures services.

Manufactured conditions are available as follows:
A - Annealed
H - Hardened and tempered at a relative low temperature.
T - Hardened and tempered at a relatively high temperature.
S - Stain hardened relatively high cold work.
B - Relatively severe cold work.

» ASTM A 314

Standard specification for stainless and heat resisting and bars for forgings.

The specification covers stainless and heat resisting steel billets and bars intended only for forgings.

» ASTM A 582

Standard specification for free machining stainless and heat resisting steel bars, hot rolled or cold finished.

Typical grades are types 303, 303SE, 416 etc. This specification covers hot finished or cold finished bars, except bars for forging. It includes rounds, square and hexagons in the more commonly used types of stainless and heat resisting free machining steel designed especially for optimum mach inability and for general corrosion and high temperature services.

» ASTM A 476

Standard specification for stainless and heat resisting steel bars and shapes for used in boilers and other pressure vessels.

The specification covers hot and cold finished bars of stainless and heat resisting steel, including rounds, squares and hexagons and hot rolled or extruded shapes such a angles, tees and channels for use in boiler and pressure vessels construction. It is also related to the ASME boiler and pressure vessel code SA-279 section II.

» ASTM A 484

Standard specification general requirements for stainless and heat resisting bars, billets and forgings.

This specification covers general requirements which shall apply to stainless and heat resisting wrought steel bars, shapes forgings and billets or other semi finished material (except wire) for forging. Pertinent details contained in this specification are tolerances for size, width, thickness, length and straightness of bars materials.

» Conditions and Surface Finishes

Stainless and heating resisting bars are produced in various conditions and surface finished. It is important that conditions be associated with the appropriate finish because each finish is not applicable to every condition.
