Product Overview
The AeroForge-TD1200 is a premium heavy-duty turbine disc engineered for extreme rotational stress, elevated temperatures, and mission-critical reliability in aerospace and power generation applications. Precision-forged from Waspaloy — a nickel-based superalloy renowned for exceptional creep resistance and oxidation stability up to 760°C — this Ø1200mm × 210mm disc meets the stringent metallurgical and quality requirements of ASTM B637 and AS9100 Rev D. Designed for high-pressure compressor and low-pressure turbine stages, the AeroForge-TD1200 delivers unmatched structural integrity under cyclic thermal-mechanical loading.
Each unit undergoes full-process traceability, including vacuum induction melting (VIM), electroslag remelting (ESR), closed-die forging, solution heat treatment, double aging, and comprehensive NDT (UT Level 3, MPI, dimensional CMM validation). Its optimized grain flow alignment and controlled microstructure ensure fatigue life exceeding 25,000 cycles at design RPM.

Applications
The AeroForge-TD1200 heavy-duty turbine disc serves as a core rotating component in next-generation gas turbine engines, industrial aeroderivative turbines, and marine propulsion systems. It is especially suited for applications demanding high-strength Waspaloy turbine disc performance at Ø1200mm scale — including LP turbine rotors in civil aviation (e.g., CFM RISE program derivatives), land-based power generation turbines, and defense-grade propulsion platforms where ASTM B637 compliance and AS9100 Rev D process rigor are non-negotiable.
