It is a steel characterized by extensive possibilities of heat treatment and excellent characteristics of use. The higher content of molybdenum (Mo) endows this steel with excellent toughness, good tempering strength, high resistance to shocks and to thermal fatigue.
It can be cooled in service with water.
Main applications:
- molds for the pressure casting of heavy alloys with high melting temperature
- liners, spindles and other parts for extrusion presses
- tooling for the production of nuts and bolts;
- single block inserts and dies for presses
