HEAT TREATMENT
Annealing: The purpose of annealing DC53 mold steel is to eliminate structural defects, improve the structure, homogenize the composition, refine the grains, improve the mechanical properties of the steel, reduce residual stress; at the same time reduce the hardness, improve plasticity and toughness, and improve cutting performance. Annealing belongs to the heat treatment of semi-finished products, also known as pre-heat treatment.
Quenching: The quenching temperature range of DC53 is 980-1010°C. It is quickly cooled after being kept warm for a period of time to obtain a martensite structure and improve the hardness and wear resistance of the material.
Tempering: The quenched DC53 mold steel is tempered. The tempering temperature is usually 150-200°C. The purpose is to adjust the hardness and toughness to achieve the best balance and improve the overall performance of the material.
FORGING
For special applications, DC53 can also be forged into many shapes. The temperature for forging is between 900° C (1,650° F) and 1,100° C (2,010° F). Annealing after forging in highly recommended to minimize stress in the part and assuring.
