Tool Steel H11 is a chromium-based steel alloy from the “H” family of steels according to the AISI classification system. H11 is one of the most commonly used alloys from this group, thanks to the outstanding impact toughness. The High Chromium and Mn Content of the steel gives it high hardness properties. The H11 properties comprises of high tensile strength. H11 steel has high chromium content due to which, it can be applied with high temperature heat treatments. The Chemical Composition of H11 steel is as follows: Element %Composition. C%: 0.33-0.43. Mn%: 0.20-0.50

Equivalent Grade : AISI H11,SAE H11, H11, 4Cr5MoSiV, DIN 1.2343, JIS SKD6 ,DAIDO SKD6 BOHLER W300

H11 tool steels are forged at 900- 1120°C .Reheat is necessary when temperature below 900°C ,AISI H11 steel should be cooled as slowly as possible in the furnace,annealing is recommended after forged. Stress relieving to remove machining stresses should be carried out by heat to 650°C, holding for one hour at heat, cooling in the furnace.

The forming characteristics of H-11 H11 AMS 6487 Tool Steel are good by conventional methods. It also may be formed by forging and machining. Welding H-11 AMS 6487 Tool Steel is a readily wieldable alloy by conventional methods.

Tool Steel H11 has minimal distortion during deep-hardening and air-hardening thanks to the balanced alloy content. H11 can also be hardened with an air quenching method
