Aisi Type 430 Stainless Steel Sheet Coil For 21 Gauge Thickness With Food Grade Bright Finish
| 430 Stainless Steel is a ferritic stainless steel with corrosion resistance approaching that of 304/304L stainless steel. This grade does not work harden rapidly and can be formed using both mild stretch forming, bending, or drawing operations. This grade is used in a variety of interior and exterior cosmetic applications where corrosion resistance is more important than strength.
430 Stainless Steel has poor weldability compared to most stainless steels due to the higher carbon content and lack of stabilizing elements for this grade, which requires post weld heat treatment to restore the corrosion resistance and ductility. Stabilized grades such as Type 439 and 441 should be considered for welded ferritic stainless steel applications. |
