W 1.2711

A HRC 40 prehardened mould steel

W1.2711 is a 40HRC pre – hardened grade for the plastic mould industry, which is characterized by:
• Higher hardness than P20 or W1.2311
• High resistance to wear
• High toughness
• Good polishing properties

The grade is delivered heat treated 360/400 HB. The steel is melted in an electric arc furnace and refined under high vacuum process (VOD) for efficient deoxidation and desulfurization. This process ensures
• A precise and consistent chemical analysis
• A very low level of oxygen
The steel is then bottom poured in ingots designed to improve chemical homogeneity during solidification, and cross rolled. Segregates concentrated in the upper part of the ingot are systematically cropped.


• Euronorm: 54 Ni Cr Mo V6
• Werkstoff: W1.2711
