Description
A HRC 40 prehardened mould steel
W1.2714 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 and 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 phosphorus and 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.
