Characteristics of the material
Belro steel is a wear-resistant tool steel produced in Austria and a general-purpose die steel for cold stamping dies. It is a cold work die steel that is used in large quantities internationally and domestically. It is an air-hardened steel. The mass fraction of carbon in this steel is as high as ., and the mass fraction of chromium is as high as . The ductility of steel is relatively weak, and compared with other excellent properties, its toughness is slightly insufficient, and the surface of the steel is difficult to mirror-polished.
The hardness can be reached.
