Application of AISI H13 Tool Steel
H13 die steel for the manufacture of large impact load die, hot extrusion die, fine forging die; Die casting moulds for aluminum, copper and its alloys.
H13 air quenched hot work die steel imported from USA. Its performance, use and 4Cr5MoSiV steel are basically the same, but because of its high vanadium content, so the performance of the medium temperature (600 degrees) is better than 4Cr5MoSiV steel, is a representative steel in the hot work die steel is widely used.

H13 Hot Work Tool Steel Properties
Electroslag remelting steel, the steel has high hardenability and thermal crack resistance, the contain higher content of carbon steel and vanadium, good wear resistance, toughness is relatively less, has good heat resistance, high temperature has good strength and hardness, high wear resistance and toughness, excellent comprehensive mechanical properties and high resistance to tempering stability.
H13 Hot Work Tool Steel Hardness Analysis
The carbon content in the steel determines the matrix hardness of the hardened steel. According to the relationship curve between the carbon content in the steel and the hardness of the hardened steel, the quenching hardness of H13 die steel is about 55HRC.
For tool steels, part of the carbon in the steel enters the steel matrix and causes solution strengthening. The other part of the carbon will combine with the carbide forming element of the alloying element to form the alloying carbide. For hot work die steels, besides a small amount of the alloy carbide remains, it is also required that it disperses and precipitates on the quenched martensite matrix to produce two hardening phenomena during the tempering process.
Thus the properties of hot work die steels are determined by the uniform distribution of residual alloying carbon compounds and the microstructure of tempered martensite. Thus, the content of C in steel should not be too low.
Heat Treatment for H13 Tool Steels
Tavlama
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 giderici
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.
Sertleşme
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.
Söndürme
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.
Temperleme
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.
