We are leading manufacturer and stockist of Aircraft Steel 4140 Normalised in China.Aircraft Steel 4140 NormalisedTechnical Data SheetAircraft Steel 4140 NormalisedChemical Composition LimitsWeight%CSiMnCrMo4140 Ann0.400.250.851.000.254140 Normalised0.400.250.851.000.25Alloy 4140 (AISI 4140) is a low alloy steel containing Chromium and Molybdenum. Alloy 4140 is the most widely used alloy for oil patch applications. Usually supplied hardened and tempered to condition T in sections up to 100mm with a tensile strength of 850 - 1000MPa and aiming for this strength range in larger sections. Alloy 4140 (AISI 4140) offers a very good balance of strength,Website:, toughness and wear resistance. Other typical applications are axles, conveyor parts, crow bars, gears, logging parts, spindles, shafts, pump shafts, sprockets, studs, pinions, rams, ring gears.Aircraft Steel 4140 Normalised Mechanical PropertiesAlloySection mmYield Strength MPaTensile Strength MPaElongation %Izod JHardness HBAlloy Alloy Alloy Aircraft Steel 4140 Normalised Specifications
