Alloy Specifications
Features
- Withstands temperatures up to 500°C
- Uses: Used for everything from resistors, heating applications, mechanical components, and springs. Type 304 is the most widely used Chromium-Nickel austenitic stainless steel. It is nonmagnetic in the annealed condition and becomes slightly magnetic when cold worked. It has excellent fabrication and weldability characteristics. Non-hardenable by heat-treating. Low carbon content minimizes problem of carbide precipitation during welding and has permitted this alloy's use in corrosive service in the as-welded condition.
