Hot and semi‑hot forging form steel, aluminum, or titanium alloys under high temperature and pressure. Durable dies and controlled heating enable strong, fatigue‑resistant parts used in automotive, aerospace, and industrial components.
Hot and semi‑hot forging are deformation processes in which metal is shaped under compressive loads to achieve high strength and precise geometries. In hot forging, billets are heated above recrystallization temperature, allowing maximum formability and eliminating strain hardening. Semi‑hot forging operates at slightly lower temperatures, reducing scale formation and improving surface finish and tolerances while still enabling significant shape complexity. Commonly processed materials include steel, aluminum, and titanium alloys selected for strength, toughness, and thermal stability. Tooling ,usually made of Hot Work Tool Steels, consists of robust dies, punches, inserts, and lubrication systems designed to withstand high loads, thermal cycling, and wear. Controlled heating, press force, and die design ensure accurate grain flow, low porosity, and high fatigue resistance. Key applications include automotive suspension parts, crankshafts, connecting rods, gears, aircraft structural components, and safety‑critical fasteners where superior mechanical properties and durability are essential.
The BÖHLER W360 AMPO is the powder equivalent of the W360 ISOBLOC. Due to its chemical composition, the material belongs to the product group of hot-work tool steels. After hardening and tempering, it can achieve a hardness of up to 57 HRC with very good toughness properties. Its high temperature wear resistance, heat resistance and toughness characterizes the material. Applications: Printed components with conformal cooling for die casting applications, wear protection layers and repair work in mold making using laser cladding.
