Steel properties

ALTA 1.2767 steel is a Chrome–nickel–molybdenum steel for hardening in the airflow with the high hardenability. The steel is characterized by a relatively high hardness after hardening, especially good toughness against the stress by pressure of shocks and hits, very good resistance to the wear and rather good dimensional stability at the heat treatment. It is rather difficult to form the steel at the heat and it shows relatively more difficult workability in the soft-annealed state.

Applications

² Cold cutting knives, scrap knives, industrial cutting knife/blades

² Highly stressed tools for cold punching, pressing of plastics, big breeze blocks and harden

² Thick plate stamping die, tableware mold, large size blanking die, hot forging dies, embossing dies 

² Hot work tools as small dies requiring high toughness at the high hardness
