SKD61 is a Japanese brand of hot work die steel, corresponding to the 4Cr5MoSiV1 (1299-2000 GB/T) is the most widely used hot die steel.
SKD61 has good toughness and high temperature fatigue performance can withstand temperature fusion, suitable for long-term work in high temperature has good cutting performance and polishing performance. SKD61 electric furnace smelting and after electric slag remelting, steel more pure, toughness better. Use suitable for manufacturing aluminum, zinc and copper alloy extrusion mode, die casting, hot forging die, and hot shear blade of the small size of Yin Liang steel (peeling, cold drawn) material is fabricated top rod, Secretary extinguishers ideal material of SKD61 is also suitable for manufacturing high yield plastic moulds nitriding nitriding process can make the mold surface obtained very good of the hardened layer, for extrusion die wear resistance and improve the corrosion resistance, the effect is very significant; for die-casting moulds nitriding treatment can significantly improve the surface corrosion resistance is conducive to product release.
KD61 chemical composition (mass fraction) is as follows (%):
