AISI 420 ​Stainless steel round bar


A leading stockholder and distributor for quality Stainless Steel and Super Duplex steels.
Located in Perth, Western Australia. We ship worldwide from stock or indent order.


420 is a martensitic stainless steel with 12% Chromium  which is sufficient to give good corrosive resistance properties. .It’s best corrosive resistance is when hardened and surface is ground or polished.It has good ductility in the annealed condition but can be hardened up to 500HB (highest of the chromium grades). Martensitic grades are known for high hardness and allowances must be made for poor weldability and usually allowances for a final harden and temper treatment. 
Steel is magnetic and welding is not recommended.
