About 4140 Alloy Steel
SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, the material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature.
Application of 4140 Alloy Steel
AISI SAE 4140 alloy steel can be made into round steel bar, flat & square steel bar, steel plate, steel tube, and has many uses in the aerospace, oil and gas and automotive industries, typical uses are thin-walled pressure vessels, forged gears and shafts (Motor shafts, pump shafts, hydraulic shafts, etc.), spindles (lathe spindles, milling spindles, etc.), collars, clamps, high strength bolts, valve bonnet, screws, nuts, worms, collets, torsion bars and various carburized parts.
