Alloy Steel AISI 4140 is a chromium-molybdenum low alloy steel, which possesses a balance of hardness, toughness, and strength. It normally has 0.38–0.43% Carbon, 0.80–1.10% Chromium, 0.75–1.00% Manganese, 0.15–0.25% Molybdenum, and 0.15–0.35% Silicon, with minute quantities of Phosphorus and Sulfur. Its physical properties are tensile strength of 655–850 MPa, good resistance to fatigue, and a Brinell hardness of 197–235 HB. The alloy is adaptable to heat treatments such as quenching and tempering, enhancing strength and wear resistance, and thus being usable in high-performance industrial uses.
