Steel properties : |
Chrome-manganese-nickel-molybdenum steel for hardening in air***in oil with good hardenability***good firmness during the heat. It is well-workable during the heat***well-workable in the soft-annealed state***it has good polishability. The steel has a high ability of the heat treatment into big depths (better than DIN 1.2311) with the balanced process of firmness around the whole cross-section. It is appropriate for nitriding***hard-chroming. |

|
Applications :
|
For Injection moulds for thermoplastics, extrusion dies for thermoplastics, plastic piping & plumbing injection molds. Blow molds, forming tools, press – brake dies (possibly flame hardened***nitrided ). Aluminium die casting prototype dies, structural components, shafts. Pet preform mold, Standard Mould Base, Compression Mould for SMC, Cavitations Molds.
