W. NR. 1.2316
CZK 0
Characteristics
Chrome-molybdenum steel for hardening in oil with very good hardenability and good firmness during the heat. The steel has the increased resistance to the corrosion regarding an increased content of chrome. The steel has the excellent resistance to the wear, good workability and polishability, for the usage it is delivered in the heat-treated state.
Suitability
Molds for pressing of chemically-aggressive plastic substances etc.
