Tool Steel Materials

Tool steels are high-carbon, high-alloy grades engineered for cutting, forming, and shaping other materials. They are classified by application and hardening method: cold work (O1 oil-hardening, A2 air-hardening, D2 high-Cr high-C), hot work (H13 for die casting and forging at 540°C), high-speed (M2, M42 for metal cutting at 600°C), shock-resisting (S7), and mold steels (P20 pre-hardened for plastic injection). Secondary hardening through multiple tempers is characteristic of high-speed and hot work grades.
