35CrMo alloy structural steel is the specification number of alloy structural steel (alloy quenched and tempered steel), which is mainly used to manufacture important parts of various machines that can bear impact, bending, twisting and high load.
35CrMo alloy structural steel has a high static strength, impact toughness and high fatigue limit. The hardenability of 35CrMo alloy structural steel is higher than 40Cr. It has a high creep strength and lasting strength at high temperature. Cold deformation plastic medium, poor weldability.
The following is 35CrMo alloy structural steel chemical composition
Carbon: 0.32~0.40, silicon: 0.17~0.37, manganese: 0.40~0.70, sulfur: permitted residual content≤0.035, phosphorus: permitted residual content≤0.035, chromium: 0.80~1.10, nickel: permitted residual content≤0.030, copper: permitted residual content ≤0.30, molybdenum: 0.15~0.25.
35CrMo alloy structural steel is used in the manufacture, high load of impact, bending and twisting under a variety of important parts in the machine, such as the rolling mill herringbone gear, hammer rod, connecting rod, crankshaft, fasteners, turbine engine shaft, axle, engine transmission parts, motor shaft, the punch in petroleum machinery, boiler bolt working temperature is below 400 degrees Celsius, less than 510 degrees of nut, high pressure seamless thick-walled pipe in chemical machinery.
