Forged Production 1.2714 Tool Steel Block In Good Toughness, Strength And High Wear Resistance
SKT4 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.
