4Cr13/420/1.2083/S136 Stainless Tool Steel Bar for Special Steel
1.2083/420 stainless tool steel is ideally suited for plastic
moulds, for acid aggressive plastics,PVC or acetates, and can be
used with plastics containing abrasive fillers. It also is suitable
to produce components for mediacal and optical applications.
Application
1. Transparent plastic mould
2. Highly stressed cutting and punching tools for thin sheets
3. Stone processing tools and knives for paper and plastics,shear
knives
4. Requiring higher food industrial equipment parts and PVC / PP /
