420 (1.4021) Stainless Steel
420 (1.4021) Stainless Steel
Stainless steel 420 1.4021 is a martensitic machining bar whose machinability is improved by the addition of Sulphur. Sulfur also improves weldability, corrosion resistance and formability, reducing the non-free machining equivalent to below 410.
