DIN 1.2344 /AISI H13/GB 4Cr5MoSiV1 Hot Rolled Forged Hot Work Tool Steel Flat Bar
Product Description
SKD61 has good toughness and resistance to high temperature fatigue performance can withstand temperature fusion, suitable for long-term work at high temperature with good cutting performance and polishing performance.SKD61 is smelted by electric furnace and remelted by electroslag, resulting in purer steel and better toughness.Use is suitable for making aluminum, zinc, copper alloy extrusion die, die casting, hot forging die, light steel and hot shear blade small specifications such as Yin (peeling, cold drawn material), is an ideal material to make plunger, ejector SKD61 high yield is also suitable for manufacturing plastic moulds nitriding treatment nitriding treatment can make the mould surface to obtain good hardening layer of tissue, improve wear resistance, corrosion resistance for extrusion die, the effect is very significant;The nitriding treatment of die casting mold can be significantly improved, and the surface corrosion resistance is conducive to rapid demould.
1. Features
a. High temperature strength and toughness, good wear resistance, easy cutting.
b. Can make the mold life longer, more stable performance, and easy to process, heat treatment deformation is small.
2. Applications
a. Suitable to manufacturing aluminum, zinc, copper alloy extrusion die, die casting, hot forging die and hot shear blades, etc.
b. Suitable for plastic mold, hot reamer, rolling knife, general hot forging die, hot bolt mold Various tools and so on.
c. H13/1.2344/SKD61/4Cr5MoSiV1 is most widely used in aluminum, zinc die-casting mold materials.
