Introduction:
H13 steel is the most popular and most versatile, hot work mould steel, providing a good balance of toughness, heat check resistance, and high temperature strength, in addition to moderate wear resistance. H13 steel can resist softening to 550°C and has good resistance to heat checking. Will Nitride with a case hardness over 1000 V.P.N. Generally supplied annealed to HB 230 max.
Process:
H13 material is softer during hot forging, in order to avoid excessive bending, the production length of ordinary forging machines is not more than 9 meters, in the case of Radial forging equipment, the H13 steel forging rounds bar can reach a maximum of 15 meters.
In production, H13 ingots need slowly cooled. After ingot release mould, it need take annealed before being forged.
As delivery for clients, H13 recommends annealing + surface bright( remove the black oxide skin), because the high nickel element is prone to surface cracking.
Size and Delivery:
Available processes: ESR (less non-metallic inclusions), PESR (less non-metallic and hazardous gas element)
Applications:
H13 steel is an air hardening, 5% chromium die steel, which is an excellent choice for a wide range of hot work and cold work applications. Typical applications include die casting dies for aluminium, magnesium and zinc, extrusion dies for aluminium and brass, liners, mandrels, pressure pads, followers, bolsters, die cases, die holders and adaptor rings for copper and brass extrusion. H13 steel is used to produce hot stamping and press forge dies, split hot heading dies, gripper dies, hot punching, piercing and trimming tools. Other applications include plastic moulds, shear blades for hot work and hot swaging dies.
General Properties:
H13 steel is characterized by
Good resistance to abrasion at both low and high temperatures.
High level of toughness and ductility Uniform and high level of machinability and polishability.
Good high-temperature strength and resistance to thermal fatigue.
Excellent through-hardening properties.
Very limited distortion during hardening.
Good machinability.
