1.4112 (R17X)

Description

It is a martensitic stainless steel with high hardenability (58 – 60 Rc).
Air hardening should be preferred for parts with complex shapes. Can be polished, usually not welded.
Wear resistance is also high.

APPLICATION AREAS

Knives and cutting tools, rollers, punch discs, which should be stainless,

As a screw and head in plastic manufacturing, in ball bearings,

Nozzles of injection molds, knives and machine parts used in the food industry
