HOT DIE STEELS ( H-11 Steels )

H-11 steels are the most commonly used Hot Die Tool Steels. These Hot Die Steels made up of the composition of various grades like Carbon, Mangnese, Silicon, Chromium. Chromium is the major chemical composition of H-11 tool steels. It contains 4.75-5.50% Chromium. It can be air hardened in 150 mm thick sections.These steels have minimal distortion during hardening due to their balanced alloy content.These steels can be cooled using water without damage. These steels have low Carbon and alloy contents with good toughness. These steels can be deep hardened by heat treatment and air-quenching.
