Diameter 20 - 400mm Annealed Hot Work Tool Steel H13 / 1.2344 / SKD61
About H13 Hot Work Tool Steel
H13 hot work tool steel for the manufacture of large impact load forging die, hot extrusion die, precision forging die; aluminum, copper and alloy die-casting mold.
Features
1) Electroslag remelting steel, the steel has a high hardenability and thermal cracking resistance, the steel contains a higher content of carbon and vanadium, good wear resistance, toughness is relatively weakened, with good heat resistance.
2) High temperature with good strength and hardness, high wear resistance and toughness, excellent comprehensive mechanical properties and high resistance to tempering stability.
3) Good resistance to high temperature tempering performance, hardness steady working under 600℃, dimensional accuracy stability durability.
4) Cold and hot fatigue resistance, strong ability to resist crack.
Applications
1) Full hardness (52-54Hrc) plastiy moulds with igh polishing and long lifetime requirements, (such as bakelite plastic mould).
2) Lead Zn and Al alloy die casting moulds (such as engine radiater, lights ang other decoration products).
3) Aluminum extruded moulds (such as Aluminum window frame, computer radiator).
4) Hot forging moulds (such as auto connecting rod, crank, stainless dinner knife).
5) Cu alloy extruded, die casting moulds.
