Electroslag Remelted (ESR) Mold Steels are high-performance tool steels produced using the Electroslag Remelting (ESR) process to achieve exceptional purity, uniform grain structure, and superior mechanical properties. Compared with conventional mould steels, ESR grades offer improved polishability, enhanced toughness, better wear resistance, and excellent dimensional stability, making them the preferred choice for precision mould manufacturing and demanding industrial tooling.

These premium steels are extensively used in plastic injection moulds, die-casting dies, medical moulds, optical tooling, automotive moulds, and engineering applications where consistent performance, long service life, and outstanding surface quality are required.
