1.2083 Steel Plastic mould Steel, DIN1.2083 Steel
- Description
Description
Main characteristics and applications.
Martensitic stainless steel with a high hardenability, good polishing properties, excellent resistance to corrosion and rust.
Its applications are plastic molds, high wear resistance cavities, particularly for processing of acid aggressive plastics (i.e. acetate and PVC), or plastics containing abrasive fillers. Suited for the manufacture of transparent plastics such as molds for optical and medical products.
