Introduction
H-13 (1.2344) is an air hardening chromium die steel - can be used for a range of applications. The higher vanadium content ensures increased resistance to heat checking and all round improvement to properties at elevated temperatures.
Steel Properties : High hot-wear resistance, high hot tensile strength and toughness. Good thermal conductivity and insusceptibility to hot cracking. Can be water-cooled to a limited extent.
Applications : Hot-work tool steel for universal use. Pressure casting dies and metal extrusion tools for processing light metals, forging dies, moulds, screws and barrels for plastic processing, nitrided ejectors, hot-shear blades. Suitable for Aluminium Extrusion Die & Aluminium Copper Forging Dies.
H13 has high hard resistance and hardness.
Suitable for Aluminium Extrusion Die, and Aluminium Copper forging Die.
