H13 Hot Work Tool Steel Usage
H13 is the introduction of the United States H13 empty hardening hardened hot for die steel. Its performance, use and 4Cr5MoSiV steel is basically the same, but because of its higher vanadium content, so the temperature (600 degrees) is better than 4Cr5MoSiV steel, hot work die steel is widely used in a representative steel.
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.
Features
Electroslag remelted steel, has high hardenability and thermal cracking resistance, contains a high content of carbon and vanadium, good wear resistance, relative toughness weakened, with good heat resistance, in the Higher temperature has better strength and hardness, high wear resistance and toughness, excellent mechanical properties and high resistance to tempering stability.
