5Cr-Mo-V is a chromium-molybdenum-vanadium alloy steel used in aircraft landing gear, fasteners, and structural components requiring high strength and fatigue resistance at ambient temperatures. The Q&T (quenched and tempered) condition delivers tensile strengths typically in the 1,400–1,900 MPa range with good fracture toughness and fatigue performance, making it suitable for highly stressed aerospace applications where weight efficiency and reliability are critical.
