H13 Tool Steel is chromium-molybdenum hot work steel with a wide range of uses in both hot and cold work tooling. Thermal fatigue cracking occurs as a result of repeated heating and cooling cycles in hot work tooling applications. H13's hot hardness (hot strength) resists this. H13 is utilized for more hot work tooling applications than any other tool steel due to its exceptional combination of high toughness and resistance to thermal fatigue cracking (also known as heat checking).

H13 is employed in a range of cold work tooling applications due to its high toughness and excellent heat treatment stability. In these applications, H13 outperforms typical alloy steels like 4140 in terms of hardenability (through hardening in large section thicknesses) and wear resistance.

Hot forging and pressing dies, extrusion dies, mandrels, and punches, hot chisels, pressure pads, extrusion stems, and rams, blanking and bending tools, hot heading tools, and backer blocks are all examples of grade application.

As the reputed die Steel H13 Flat Bar suppliers, we ensure that the hardness tests were performed on 1-in. round H13 specimens that were air quenched from 1850°F and tempered for two hours at different temperatures.

H13 tool steels are heated to a temperature of 816°C (1500°F). The steels are then heated directly by raising the temperature to 1010°C (1850°F) and holding for 15 to 40 minutes. After that, the steels are air-quenched.

Hardening and Tampering:

H13 tool steel is a high-hardenability steel that should be hardened by cooling in calm air. To reduce decarburization, a salt bath or controlled environment furnace is preferred, but if neither is available, pack hardening in spent pitch coke is recommended. Depending on the size of the part, the temperature used is usually 1800°-1850°F.

Tempering, on the other side varies depending on the size and use, although it is normally done in the range of maximal secondary hardness or above. It is suggested that you temper twice. H13 that was air quenched from 1800°F and tempered for 4 hours at various temperatures is shown below. The results can be used as a guide; however keep in mind that the hardness of some areas of a heavy chunk or bulk may be several points lower.

H13 tool steels are forged at a temperature of 1079°C (1975°F). Forging below 898°C (1650°F) is not recommended for this grade of steel.

When machining strains are desired, heat steadily to 1050°-1250°F, allow equalizing, and then cooling in quiet air (Strain Relieving). H13 tool steels are annealed at 871°C (1600°F) in the furnace and then slowly chilled at 4°C (40°F).
