1.2344 EF S/E SU
X40CrMoV5-1 / AISI: H 13 / JIS: SKD 61
Delivery Method : Normalized, annealed 180-230HB
Uses : It is a standard hot work tool steel with high thermal conductivity and abrasion resistance. It is widely used in injection molds of light metals, hot cutting knives, molds where some non-ferrous metals are forged, aluminum profile molds and metal extrusion presses. The surface of this material, which has high impact resistance, can be hardened by nitration process.
*Time interval varying depending on the section
