25CrMo 35CrMo Seamless Alloy Steel Pipe
25CrMo alloy steel pipe is a high-quality alloy steel for engineering machinery structures with excellent properties such as high strength, high toughness and high heat resistance. The steel pipe is composed of various alloy elements such as chromium and molybdenum. The common chemical compositions are as follows: C: 0.22-0.29, Si: ≤0.40, Mn: 0.60-0.90, Cr: 0.90-1.20, Mo: 0.15-0.30. 25CrMo alloy The mechanical properties of structural steel pipes are as follows: Yield strength: ≥600 MPa, Tensile strength: ≥900 MPa, Elongation: ≥14%, Area reduction rate: ≥55%, Impact absorbed energy: ≥68 J, Material Brinell hardness : 229. 25CrMo seamless alloy steel pipe can obtain good comprehensive properties through quenching and tempering, and has broad application prospects.
35CrMo Seamless alloy Steel pipe is used to manufacture important parts in various machines that withstand impact, bending and torsion, and high loads, such as rolling mill herringbone gears, crankshafts, hammer rods, connecting rods, and fasteners. The operating temperature is below 400 degrees Celsius. Boiler bolts, nuts below 510 degrees Celsius, high-pressure seamless thick-walled pipes in chemical machinery (temperature 450~500 degrees Celsius, non-corrosive media), etc.
