Alloy Steel AISI 8740 | UNS# G87400 is similar to AISI 4140 and is generally used for aircraft fasteners and engine bolts, piston rods, axles, tool joints, and other applications where strength, toughness, and wear resistance are top priorities. As a nickel-chromium-molybdenum low-alloy steel, AISI 8740 demonstrates high tensile strength, good yield strength, fatigue resistance, toughness, and wear resistance properties.
