H13 | 1.2344 | SKD61 Tool Steel
1.CHARACTER
DIN 1.2344 tool steel (also known as AISI H13 steel or just H13[1]) is a tool steel grade standardized for hot working. High-alloy, hot-work steel, high heat resistance, high wear resistance, good toughness, thermal conductivity and hot cracks resistance, limited use for water cooling; for very high requirements available in grade *ESR (Electro-Slag Remelted)
Surface Finish: Black, Rough Machined, Turned or as per given requirements.

4.AISI H13 Tool Steel Heat Treatment
Annealing
Heat slowly to 1550°-1650°F, hold until entire mass is heated through, and cool slowly in the furnace (40F per hour) to about 1000°F, after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
Stress Relieving
When desirable to relieve the strains of machining, heat slowly to 1050°-1250°F, allow to equalize, and then cool in still air (Strain Relieving).
5.H13 Tool Steel 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.
