H13 /1.2344 /SKD61 Annealing Machinery Hot Work Tool Steel Round Bar
1.2344 H13 SKD61 4Cr5MoSiV1 Flat Bar Round Bar Tooling Steel belong to multi functional Machinery chromium hot work tool steels which are much widely using on hot and cold work tooling applications. 1.2344 H13 SKD61 4Cr5MoSiV1 tool steel is classified as range H steels by the AISI classification system range.This range of steels start from H1 to H19.
In steel Flat Bar Round Bar 1.2344 H13 SKD61 4Cr5MoSiV1, the molybdenum & vanadium acting as strengthening. The chromium content assists Hot Work Tool Steel Flat Bar Round Bar steel 1.2344 H13 SKD61 4Cr5MoSiV1 to resist softening when using at high temperatures. 1.2344 H13 SKD61 4Cr5MoSiV1 die steels offers outstanding combination of shock and abrasion resistance, and possesses good red hardness. It's capable of withstanding rapid cooling and resists premature heat checking. Tool Steel H13 has good machinability, good weldability, good ductility, and can be formed by multi function Machinery conventional means.
Due to Flat Bar Round Bar 1.2344 H13 SKD61 4Cr5MoSiV1 tooling steel excellent combination of very high toughness & fatigue resistance, AISI H13 hot work tooling steel is using much more than other tooling steel in tooling multi functional applications.
