Characteristics
Chrome-manganese-nickel-molybdenum steel for hardening in air or in oil with good hardenability and good firmness during the heat. It is well-workable during the heat and well-workable in the soft-annealed state and has good polishability. The steel has a good ability of the heat-treatment into big depths (better than W.Nr.1.2312), with the balanced process of firmness around the whole cross-section. It is appropriate for nitriding and hard-chroming.
Suitability
Převážně zušlechtěná na pevnost od 1050 až 1250 N/mm2 se používá na velké formy pro vstřikování plastů a velké rámy forem.
