Product Overview
The AeroForge-SF700 Structural Forging is a high-integrity, precision-engineered component designed for mission-critical aerospace and heavy-industrial applications. Manufactured to ASTM A193-B25 specification — a chromium-molybdenum steel grade renowned for exceptional tensile strength, creep resistance, and thermal stability — this forging delivers uncompromising performance under extreme mechanical and thermal loads. As part of our premium aerospace forgings portfolio, the AeroForge-SF700 undergoes full heat treatment per AMS 2750D pyrometric requirements, ensuring precise temperature uniformity, repeatable microstructure control, and certified mechanical properties across the entire cross-section.
This heat treated structural forging features a robust cylindrical geometry (700mm Ø × 1200mm height), optimized for axial load-bearing structures such as landing gear mounts, engine support frames, and primary airframe spools. Its seamless grain flow, achieved through closed-die hot forging and controlled cooling, maximizes fatigue life and fracture toughness — essential attributes for structural forgings in certified aviation platforms.
