SUS420J2 Stainless Steel Material Inner circular shape Wafer Metal Ring Special Shape Metal Ring Protect Edges Of Wafers And Chips ES-WFR-SUS420
1. Introduction of SUS420J2 Stainless Steel Material Inner circular shape Wafer Metal Ring Special Shape Metal Ring Protect Edges Of Wafers And Chips ES-WFR-SUS420
Wafer frame ring ES-WFR-SUS420 is made of SUS420J2 high hardness stainless steel plate, which can ensure the right performance as wafer metal ring.
SUS420J2 is a martensitic stainless steel with excellent mechanical properties and corrosion resistance, widely used in industrial fields. Its chemical composition and physical properties endow it with good comprehensive performance, and the heat treatment process has a significant impact on its performance.
SUS420J2 is a material defined in the Japanese Industrial Standards (JIS) and belongs to the 420 series stainless steel. It has high hardness, strength, and wear resistance, and also has good corrosion resistance under certain conditions.
