Properties
Sverker 21 is characterized by high compressive strength, high surface hardness after hardening, good though-hardening properties and high wear resistance (abrasive type of wear profile). These characteristics combine to give a steel suitable for the manufacture of medium run tooling for applications where abrasive wear is dominant and the risk of chipping or cracking is not so high, e.g. for blanking and forming of thinner, harder work materials.
Application areas
It is a 12% chromium steel suitable for medium production volume tooling where the production materials cause abrasive wear and the risk of chipping is not so high.
