What is 4140 Seamless Steel Tube?

AE 4140 (AISI 4140 steel) is a Cr-Mo series (chromium-molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, quenching deformation is small, high creep strength and high temperature endurance strength.Alloy steel 4140 is a grade 4140 alloy steel with a carbon C of 0.33-0.48.
4140 Alloy Steel Pipe Uses
AISI SAE 4140 alloy steel tube can be made into round bars, flat and square steel bars, steel plates, steel pipes, in the aerospace, oil and gas and automotive industries have a variety of uses, typical uses are thin-walled pressure vessels, forging gears and shafts (motor shafts, pump shafts, hydraulic shafts, etc.), spindles (lathe spindles, milling spindles, etc.), collars, fixtures, high-strength bolts, valve covers, screws, nuts, worms, collets, twist rods and a variety of carburized parts. Torsion bars and various carburized parts.

Used in the manufacture of 35CrMo steel requirements than the higher strength and tempering cross-section of the larger forgings, such as locomotive traction with large gears, supercharger transmission gears, rear axle, loaded with a great deal of connecting rods and spring clamps, but also can be used for 2000m below the oil deep-well drilling rod joints and salvage tools, and so on.
