75Cr1 tool steel is widely used in saw blades in industries such as mining, metallurgy, and building materials. These saw blades are subjected to enormous radial and axial stresses during operation, thus requiring high elastic limits, stiffness, fatigue strength, hardness, and tempering stability. This also puts forward strict requirements for the purity, composition segregation control, metallographic structure, and high-temperature deformation resistance of steel.
For 75Cr1 tool steel, the recommended heat treatment temperature range is 700-720 ℃. After annealing treatment, its hardness can reach 200HBS, which is usually achieved through spheroidization annealing process. In actual production, temperature control may need to be adjusted appropriately, with a heating temperature of 720 ℃ being suitable.
