It is the oldest cold tool steel that can be hardened without loss of size. It has high pressure and abrasion resistance.
It is used for crushing and grinding tools, as well as hammers of crushers and jaws for soft grinding and crushing. Also as punch material are punching tools of high-hardness materials (especially hard-shaped tools for cutting, such as transformer metal sheets and metal sheets of stainless steel), sheet metal cutting knives and steel strips with a thickness of about 4 mm, knives for wire cutting, etc
It is the oldest cold tool steel that can be hardened without loss of size. It has high pressure and abrasion resistance.
It is the most widely used steel of the cold work group, which stands out with its high wear resistance.
It has excellent surface hardenability. It is mostly preferred in automotive molds.
It is a suitable material for patterning with very good polishability and hardenability.
During heat treatment, there is very little change in size, it has high toughness.
