Hot Forging Mould Tool Steel
Fushun are main manufacturer of tool steel for Hot Forging Mould.
What is Hot Forging Mould?
Hot forging moulds are specialized tooling systems designed for shaping metal components at elevated temperatures, typically above the material’s recrystallization temperature. These moulds incorporate sophisticated designs with carefully engineered cavities, flash gutters, and cooling channels to manage thermal stress and material flow. The mould assembly must withstand extreme temperatures and pressures while maintaining dimensional stability throughout repeated forging cycles.
The primary purpose of hot forging moulds is to produce complex-shaped components with excellent mechanical properties and material grain flow. They are extensively used in automotive, aerospace, and heavy industries to manufacture critical components like crankshafts, connecting rods, and turbine blades. Hot forging allows for significant material deformation with lower forming forces compared to cold forging, enabling the production of larger and more complex parts. The process can achieve near-net-shape components while optimizing material properties through controlled deformation and cooling.
The mould materials for hot forging applications contain carefully balanced combinations of alloying elements to withstand severe thermal and mechanical stresses. Premium grade hot-work tool steels are used, incorporating chromium, tungsten, molybdenum, and vanadium to provide optimal performance at elevated temperatures. These materials offer excellent hot hardness, thermal fatigue resistance, and toughness at high temperatures. The microstructure features thermally stable carbides that maintain hardness and wear resistance under repeated heating and cooling cycles. Special surface treatments and coatings are often applied to enhance thermal shock resistance and reduce friction during the forging process, while sophisticated heat treatment processes ensure optimal performance under extreme working conditions.
