Product Details

Prehardening 1.2311, P20, 3Cr2Mo Plastic Mold Steel for Injection Mould

Prehardening 1.2311 P20 3Cr2Mo tooling steel is a common alloy tool steel which usually supplied in QT condition. The 1.2311 P20 P20 3Cr2Mo can give an excellent polished finish.Forging prehardening tempering 1.2311 P20 P20 3Cr2Mo tool steel is one of the most widely used material for machine cut plastic moulds. This grade also provides excellent wear resistance.
