H13 Steel is a hot work tool steel. H13 is equivalent with JIS SKD61, GB 4Cr5MoSiV1 and DIN 1.2344 Tool Steel. H13 Tool Steel consists of chromium, molybdenum and vanadium and is known for its high hardenability and great toughness.
The molybdenum and vanadium act as strengthening agents while the chromium content helps the H-13 tool steel to withstand softening when used at high temperatures. It also combines shock and abrasion resistance, has good red hardness, can resist rapid cooling and withstand premature heat checking. The H13 tool steel has good machinability, good weldability and good ductility and it can be formed by conventional means. So H13 tool steel applications is very range in hot forged mold, hot work tool.
