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.
Special strengthening elements vanadium and molybdenum are added, and the wear resistance is extremely excellent. It is suitable for making aluminum, zinc, copper alloy extrusion dies, die casting dies, hot forging dies, and hot shear blades.
