3. Main 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 it has good polishability. The steel has a high

ability of the heat treatment into big depths (better than W.Nr.1.2311) with the balanced

process of firmness around the whole cross-section. It is appropriate for nitriding and

hard-chroming.

4. Applications

Plastic injection moulds with high mirror surface requirements, large injection and

compression moulds for plastic processing over 400 mm thickness such as bumpers,

insturment panels, garbage containers, dashboards, waste bins, chairs, bottle crates,

television cabinets etc., mould carrier frames for the plastic moulds, components for

general mechanical engineering and tool manufacture, synthetic plastic moulding dies,

pressure casting frames, hydro forming tools, structural components, shafts, blow moulds,

extrusion dies for thermoplastics.
