H13 ESR

Overview

H13 ESR (Electro Slag Remelted) Steel is a premium-grade hot work tool steel manufactured through the ESR process to achieve exceptional cleanliness, uniformity, and mechanical properties. Renowned for its outstanding toughness, high-temperature strength, and superior resistance to thermal fatigue and wear, H13 ESR is widely used in demanding applications such as die-casting dies, forging tools, extrusion dies, hot shear blades, and plastic moulds. The ESR process significantly reduces impurities and improves microstructural consistency, resulting in enhanced polishability, machinability, and extended tool life. With excellent resistance to heat checking and cracking under extreme operating conditions, H13 ESR Steel is the preferred choice for high-performance tooling and precision engineering applications across automotive, aerospace, and manufacturing industries.
