Product Description
SKD61 H13 1.2344 Tool Steel Plate
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.

7: H13 Steel 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.
8: H13 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). Â
Preheat Prior to Hardening
Warm slightly before charging into the preheat furnace, which should be operating at 1400°-1500°F.
Hardening
H13 tool steel is a steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested. The temperature employed is usually 1800°-1850°F, depending on size section.
Quenching
Quench in still air or dry air blast. If complicated forms are to be hardened, an interrupted oil quench can be used. Quench part in oil and remove from bath when it just loses its color (1000°-1100°F). Finish cooling to below 150°-125°F in air, then temper immediately.
Tempering
Tempering practice may vary with size and application, but is usually performed in the range of maximum secondary hardness or higher. Double tempering is recommended. The results below is H13 that was air quenched from 1800°F and tempered for 4 hours at various temperatures. The results may be used as a guide, keeping in mind that parts of heavy section or mass may be several points lower in hardness.
