Stainless Steel 420 Square Bar

Stainless Steel 420 Square Bar Stainless Steel 420 Square Bars, also known by their UNS S42000 designation, are high-carbon martensitic stainless steel renowned 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 provides a perfect balance of affordability and reliability.

The 420 Square Bar is essential in the manufacture of components requiring high wear resistance and precision machining. Its typical applications include the production of cutlery, surgical instruments, valves, gears, and shafts. The square shape provides uniform strength and stability, making it ideal 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.
