Home / 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.
