Due to the presence of a large amount of eutectic carbides in high alloy tool steel with pearlite, sufficient fragmentation can only be achieved through significant deformation; On the other hand, due to the influence of its alloy composition, high alloy tool steel with martensite has low plasticity, high deformation resistance, poor thermal conductivity, and high tissue stress during cooling. It is prone to defects such as cracks in the forging production process. Thus creating a contradiction that complicates its forging process. Therefore, when formulating the forging process for this type of steel, corresponding technical measures should be developed from each link to address this contradiction and ensure the quality of its forgings.

Technical conditions for raw material supply

1. High speed steel and Cr12 cold work die steel are generally delivered in an annealed state. Among them, hot-rolled and forged high-speed steel bars can also be delivered after annealing and processed by other processing methods (such as peeling, light drawing, polishing, etc.).

2. The surface of hot-rolled and forged high alloy steel with Lai's body shall not have visible cracks, folds, scars, and inclusions. If there are any of the above defects, they must be removed according to the standard regulations.

3. The fracture grain of chromium 12 cold work die steel should be uniform and fine, without visible shrinkage, inclusions, delamination, cracks, bubbles, and white spots. When conducting low magnification acid leaching inspection, the above defects shall not be present.

Heating of Leyte alloy tool steel billets

Laishi high alloy tool steel is prone to overburning when heated, because the eutectic structure of high-speed steel begins to melt at 1300 ℃ and chromium 12 steel at 1155 ℃, and cracking is prone to occur when forging near these temperatures. Therefore, the heating temperature should be strictly regulated, and the final forging temperature should be controlled to ensure the heating quality of the forgings.

Forging of Leyte High Alloy Tool Steel

Common forging methods: unidirectional upsetting, unidirectional elongation, repeated rolling and flattening after upsetting, axial repeated upsetting, radial cross forging, comprehensive forging method, three-way upsetting method.
