parameters
1.2344 H13 Hot work steel SKD61 8407 ESR Tool and Die Flat Alloy steel Round Bar
1.2344 is a die steel for pressure and heat. The steel is remelted by electroslag, the material is uniform, the hardenability is good, it has excellent machinability and polishing performance, high toughness and plasticity, good high and low temperature wear resistance and high temperature fatigue and heat resistance.
Vacuum degassing refining treatment is pure steel.
Spheroidizing annealing softening treatment, good cutting performance.
The special strengthening elements vanadium and molybdenum are added, and the wear resistance is extremely excellent.
1.2344/SKD61/H13 has good toughness and high temperature fatigue resistance, can withstand temperature fusion, suitable for long-term work at high temperature with good cutting performance and polishing performance. 1.2344/SKD61/H13 is smelted in an electric furnace and remelted by electroslag. The steel is purer and the toughness is better. It is suitable for making aluminum, zinc, copper alloy extrusion dies, die casting dies, hot forging dies, and hot shear blades and other small specifications of bright and bright steel (peeling, cold drawing) materials, which is an ideal material for making jacks and cylinders. 1.2344/SKD61/H13 is also suitable for manufacturing high-yield plastic molds. Nitriding treatment can achieve a good hardened layer structure on the surface of the mold. For the extrusion mold to improve wear resistance and corrosion resistance, the effect is very significant; for die-casting mold nitrogen Chemical treatment can be significantly improved, surface corrosion resistance is conducive to rapid release of products.
1.2344/SKD61/H13 hot work die steel has beautiful metallic luster, 1.2344/SKD61/H13 series products include: thimble, guide post, guide sleeve, cylinder, punch pin, floating pin and other precision high temperature resistant parts
