What does ASTM A276 mean?
The ASTM A276 specification is for hot-finished or cold-finished stainless-steel bars except for bars for reforging. This includes round squares， hexagons， and hot-rolled or extruded shapes such as angles， tees and channels that are commonly used types of stainless steel.
Bars shall be furnished in one of the following conditions:
1 Condition A — Annealed.
2 Condition H — Hardened and tempered at a relatively low temperature.
3 Condition T — Hardened and tempered at a relatively high temperature.
4 Condition S — Strain Hardened–Relatively light cold work.
5 Condition B — Relatively severe coldwork.
Stainless Steel 304 and stainless steel 304L are formed with a combination of nickel-chromium-carbon， both are used as general stainless steel with standard resistance to most corrosive environments as well as to organic and inorganic chemicals and to food and drinks.
