Overview
The 420F is a "cutting grade" martensitic steel which resembles Brandt’s earliest high- chromium stainless steel. Also used for surgical knives, it can be done very brightly. SUS420F is a stainless steel type which improves the cutting performance of SUS420J2 steel. SUS420F equals to GB Y3Cr13 in China.
Features of Inox 420F
Due to its high carbon content, 420F stainless steel features high strength, hardness and wear resistance, but a relatively poor corrosion resistance. It is generally used on some parts that have high requirements on mechanical properties but mediocre requirements on corrosion resistance. This type of steel is generally used after quenching and tempering.
