Hot Forged Die Steel Block SKD61 H13 4Cr5MoSiV1 1.2344 X40CrMoV5-1
1: H13 steel introduction
AISI H13 is a chromium-molybdenum-vanadium hot work tool steel as per ASTM A681 standard.It has good resistance to abrasion at low and high temperature,good toughness, and good resistance to thermal fatigue cracking (also known as heat checking).H13 provides excellent machinability with constant hardness during production activities,and also has excellent through-hardening properties and very limited distortion during hardening.

| Application |
H13 hot work tool steel has excellent properties which is widely used in 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 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. |
