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.

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.
Hardening: H13 tool steel should be hardened by cooling in still air. 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.
Tempering: Double tempering is recommended. Usually performed in the range of maximum secondary hardness or higher.
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned. For hot forged plate, the delivery condition is typically annealed with a milled surface.
