Die steel is used to make cold die, hot forging die, die casting die and other steel types. Moulds are the main processing tools for manufacturing parts in machinery manufacturing, radio instruments, motors, electrical appliances and other industrial sectors. The quality of the mold directly affects the quality of the pressure processing process, the accuracy of the product, and the production cost. The quality and service life of the mold are mainly affected by the mold material and heat treatment in addition to the reasonable structure design and processing accuracy.

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.

 

7: Delivery condition
    For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
    For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.

    For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
