6. Applications
1.2344 H13 SKD61 4Cr5MoSiV1 Flat Bar Round Bar Tooling Steel belong to multi function 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 die 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 tool steel
excellent combination of very high toughness and fatigue
resistance, AISI H13 hot work tooling steel is using much more than
other tooling steel in tooling multi functional applications.
