718H
Tool and Die Steel
718H is a vacuum-melted, ferrite-aluminum alloy steel that undergoes quenching and tempering before shipment. Ultrasonic testing confirms uniform hardness and metallographic structure, and it easily achieves a mirror finish. It offers the following advantages: no risk of quenching cracking or heat treatment deformation, no heat treatment costs, shortened mold production cycle, reduced mold costs (no need for deformation correction), easy mold modification, and nitriding and surface hardening treatments to increase mold surface hardness and wear resistance.

1. Product Introduction: 718H is a vacuum-melted, ferrite-aluminum alloy steel. It undergoes quenching and tempering treatments before shipment, and ultrasonic testing confirms uniform hardness and metallographic structure. It also easily achieves a mirror finish. It offers the following advantages: no risk of quenching cracking or heat treatment deformation, no heat treatment costs, shortened mold production cycle, reduced mold costs (no deformation correction required), easy mold modification, and can be nitrided and surface hardened to increase surface hardness and wear resistance.
2. Main features: uniform quality and high purity, excellent polishing performance and photoetching performance, good electrical processing performance and leather grain processing performance.
