100% UT Test Forged Production SKT4 Tool Steel Round Ring For Hot Die

SKT4/ 1.2714 / 5CRNIMO steel has good toughness, strength and high wear resistance.Its mechanical properties are almost the same at room temperature and at 500 ~ 600℃.When heated to 500℃, the hardness of HB300 can still be maintained

Hardness

Annealing,241 ~ 197HB, indentation diameter 3.9 ~ 4.3mm

Heat treatment specification and metallographic structure:

Heat treatment specification: quenched, oil cooled at 830 ~ 860℃.

Delivery status: steel is delivered in annealed condition.

Application:

Suitable for manufacturing complex shapes, large impact load, low working temperature, side length & GT;400mm large and medium-sized hammer forging die and edge cutting die.For manufacturing simple shape general manufacturing process smelting use vacuum refining process to ensure the purity of steel;The e use of large-scale professional heat treatment to obtain the best pre-hardening effect of steel, hardness uniform distribution.

-Heat to 800°Cand hold at temperature for 1/2 h to 1 h;

-Furnace cooling to 670°Cand hold at temperature for at least 10 hours;

-Cool by 10°C/h to 630°C;

-Cooling in air.

Maximum hardness:≤240 HB

Stress relieving:

To be carried out after maching before the final heat treatment.

-Heat to 600-650°C, hold for 4-6 hours;

-Cooling in furnace to 300-350°C;

-Cooling in air

Hardening:

-Initial preheating to 350-450°C;

-Second preheating to 650-750°C;

-Heat to hardening temperature 860-890°Cand hold at temperature;

-Cooling in hot oil (40-60°C); Tempering hardness: 45~45HRC

Tempering:

Tempering must be carried out within one hour from hardening(warm part)

in the range 550-630°Cfor 4-6 hours according to hardness required, the

dimensions of the parts and operating conditions.
