Properties:

Martensitic stainless chromium steel for plastic moulds, high corrosion resistance than 1.2083, resistant to chemical attack, excellent wear resistance, uniform hardness in all dimensions, etch grainable and easy to machine, high surface finish and polishability. Not suitable for nitriding and chrome plating because of the high chrome content. This grade can be produced on request by the process in hardened and tempered, soft annealed and ESR condition.

 

Applications: 

Moulds for chemically aggressive plastics and plastics containing abrasive fillers, slit dies, profile dies, drop forging tools, blowing moulds, mould inserts, moulds and extruding tools for corrosively acting plastics such as PVC amino plastics and similar materials
