H13 1.2344 SKD61 Die-casting Forged Hot Work Tool Steel flat bar
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.
H13 is a hot work tool steel, the implementation of standards GB /
T1299-2000; Grade 4Cr5MoSiV1; alloy tool steel referred to as
synthetic steel, carbon steel is based on the addition of alloying
elements and the formation of steel. Including synthetic steel,
including: Measuring Tool and Cutting Tool steel, impact-resistant
tool steel, cold work tool steel, hot work tool steel, non-magnetic
die steel, plastic mold steel.

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.
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,
4) Hot forging moulds (such as auto connecting rod, crank,
stainless dinner knife).
5) Cu alloy extruded, die casting moulds.
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.
