440A Stainless Steel Round Bar Specification
| Standards | Designation |
|---|---|
| ASTM | A 276 |
| Length | Diameter |
|---|---|
| 2-12m | 6mm-500mm |
| Type | Certification |
|---|---|
| 440A Stainless Steel Round Bar | ISO 9001:2008 |
|
Grade |
Why it might be chosen instead of 440C |
|---|---|
| 440A/B | Slightly softer and more corrosion resistant grade needed |
| 440F | High machinability required, with same hardness and hardenability as 440C |
| 420 | Lower strength and hardness needed than any of the 440 grades |
| 416 | Higher machinability required, and the much lower hardness and strength is still adequate |
