What is H13 ESR Tool Steel?
H13 ESR is a high-purity, electro-slag remelted (ESR) variant of standard H13 tool steel, offering superior cleanliness, improved toughness, and better isotropic properties. The ESR process refines the steel’s structure, making it the preferred choice for high-performance hot work tooling, die casting, and plastic molds requiring exceptional thermal and mechanical properties.
We offer outstanding wear resistance and low friction through our DLC and PVD ultrafine coatings, ideal for hot work tooling where lubricants cannot be used, ensuring longer tool life and consistent performance in demanding molding processes.
