Stainless Steel 420 Plates

Stainless Steel 420 Plates Stainless Steel 420 Plates, recognized by their UNS S42000 designation, are high-carbon martensitic stainless steel known for their excellent corrosion resistance, high strength, and ability to be hardened through heat treatment. These properties make them an ideal choice for various industrial applications requiring durability and moderate corrosion resistance. Composed of iron, chromium, and carbon, 420 stainless steel offers a balance of affordability and reliability.

The 420 Plate is crucial in the manufacturing of components where high wear resistance and precision machining are necessary. Typical applications include the production of cutlery, surgical instruments, valves, gears, and shafts. The flat shape provides uniform strength and stability, making it perfect for mechanical assemblies and high-stress installations. The material's ability to be hardened through heat treatment further enhances its mechanical properties, making it suitable for high-impact and high-stress environments.
