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 |

Stainless Steel Bar Specifications |
|||
|---|---|---|---|
ASTM A276 |
This specification encompasses cold-finished or hot-finished bars, including 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. | ||
ASTM A479 |
This specification includes cold and hot finished stainless steel bars, including rounds, squares, and hexagons, and hot-rolled or extruded shapes such as angles, tees, and channels. | ||
ASTM A484 |
This specification includes wrought stainless steel bars, shapes, forgings, and billets or other semi-finished materials, except wire, for forging. The materials are available in four types of conditions. | ||
ASTM A582 |
This specification includes cold or hot finished bars, which are suitable for machining processes. This specification includes rounds, squares, and hexagons, from common types of stainless free-machining steels. | ||
ASTM B473 |
This specification includes nickel alloy bar & wire, which can be produced in a solution-annealed condition, stabilized-annealed condition, or annealed condition. | ||
