Steel for aerospace applications encompasses high-strength low-alloy (HSLA), martensitic, and precipitation-hardening (PH) grades — including 300M, 4340M, and 17-4 PH — used in undercarriage structures, fasteners, shafts, and actuator components, with processing routes covering vacuum arc remelting (VAR), carburising, nitriding, and shot peening to meet exacting fatigue and fracture-toughness requirements.
