Abstract

The invention discloses a heat treatment process for 8DeOp mold steel, which comprises the following steps: (1) prepare a box-type resistance furnace, put 5 pieces of 8DeOp steel into the box-type resistance furnace as a group; (2) gradually heat to 830-850°C, keep warm for 10min, then apply 100-110HZ, 800V electric field sawtooth wave for 5-8min; (3) put it out of the furnace into a nitrate quenching tank with a magnetic field for isothermal quenching, keep warm for 2h; (4) at 250- Temper twice at 280°C for 2 hours each time. The heat treatment process method is simple, can improve the properties of the 8DeOp die steel in all aspects, and shorten the process time.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an 8DeOp die steel heat treatment process. Background technique [0002] 8DeOp steel is a high-carbon low-alloy cold work die steel. Since 8DeOp steel contains De elements and Op elements, 8DeOp steel has high hardenability and hardenability. Among them, De elements can increase the hardness of steel and play a role in solidification. At the same time, due to the addition of De alloy, the critical point of the steel is increased, and the amount of residual austenite after quenching is small, which improves the tempering stability of the steel. De alloy can also refine the carbide of steel, which is beneficial to improve the wear resistance and plastic deformation resistance of steel; Op can improve the hardenability and wear resistance of steel, and has the ability to enhance the corrosion resistance and oxidation resistance of steel, and Better temper stability. [0003] At present,...
