Product Description

Description:
Martensitic stainless chromium steel for plastic moulds, high corrosion resistance than 1.2083,
resistant to chemical attack, excellent wear resitance, 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.
