Principal Feature:
AISI O7 is a high-carbon alloy tool steel with good toughness, good tempering stability, and small deformation during heat treatment. The carbide distribution in this steel is uniform, and the carbide network is not easy to precipitate, and it is easy to eliminate by normalizing. The network and coarse carbide structure can be eliminated by normalizing. This steel has good forging properties. Because it is easy to decarburize, it needs to be heated in a neutral atmosphere or protective atmosphere furnace. By applying forging heat quenching and tempering treatment, a fine tempered sorbite structure can be obtained, which simplifies the process, saves time and energy, and has both good cutting performance and ideal waste heat treatment structure.
Typical Application:
AISI O7 alloy tool steel can be used to manufacture tools with complex shapes, small deformation, high wear resistance, and low-speed cutting, such as drill bits, thread tools, reamers, die, taps, thread rolling plates, and thread rolling wheels. (Plastic mold steel can be used for ejector rods to manufacture plastic films with large sizes, complex shapes and high precision requirements..
