Automotive manufacturing uses tool steels (like P20, 1.2083, 1.2316, 1.2344, D2, O1) to build different kinds of injection molds, extrusion dies, die-casting molds, forging dies ,blanking, piercing, and forming dies etc., and special steels (like case-hardening and QT alloys like 4140 4340) to build the high-performance engine and drivetrain components. This combination enables efficient, high-volume manufacturing of durable vehicles.
