SUS420J1 is a kind of stainless steel, which is a kind of martensitic stainless steel. It is a stainless steel grade specified by the Japanese Industrial Standard (JIS).
Due to its high hardness, wear resistance and corrosion resistance, SUS420J1 is widely used in the manufacture of high-strength, high-hardness parts.It is often used in the production of knives, industrial blades, injection molds, medical equipment and other fields.
It should be noted that although SUS420J1 is stainless steel, its corrosion resistance is not as good as that of steel such as AISI 304 or 316L. Therefore, it is necessary to avoid prolonged exposure to wet or corrosive environments during use.
