35CrMo Alloy Structural Steel
35CrMo steel is an alloy structural steel with high strength, high hardenability and good toughness, which is often used for engineering purposes. It has good comprehensive mechanical properties after quenching and tempering, and small temperature impact toughness. This kind of steel also has high fatigue limit and multi-impact resistance after proper heat treatment, and good low temperature impact toughness. The products commonly used in the manufacture of aeronautical parts, screws and nuts have high requirement on the comprehensive mechanical properties and fatigue performance of this kind of materials, and 35CrMo can meet their needs well.
35CrMo has high static strength, good fatigue strength and durability, good cold and hot impact toughness and low notch sensitivity, good deep hardenability, good machinability and weldability, and good fatigue crack propagation resistance. Its high static strength and impact toughness (not worse than 16J) make it eddy current loss of hard and brittle ferrite, excellent machinability. Its carburizing and hardenability are better than that of 40Cr, and its intensity is higher than that of 40Cr after quenching and tempering.
35CrMo is mainly used to manufacture important parts, such as gears, shafts, piston pin and fasteners, high-loaded transmission parts, turbine blades and large load of connecting rods and so on. For example, it is used to manufacture turbine blades of high pressure, large forgings of compressor and the connecting rod of locomotive traction. 35CrMo steel is recommended by the engineering and construction department of the Ministry of Energy.
35CrMo is a kind of alloy structural steel which can be quenching and tempering. After quenching and tempering, the steel grade can reach tensile strength of 1100MPa or more, and can be used for circumferential organic mortar, straight shaft and axles of heavy machines. The steel grade has good impact toughness and weldability; it can resist fatigue load and has low sensitivity to notch; it is suitable for work parts with large load and high wear resistance under dual alternating load. It is usually used to manufacture parts with certain fatigue strength, such as connecting rod, toothed axle and gear with high accuracy and hardness.
35CrMo has good machinability, its cutting performance is stable and reliable; the cutting tool has good wear resistance and oxidation resistance. It can realize the turning, milling and drilling, which is beneficial to the formation of parts and improve the accuracy of parts. Its reliability and stability are good and it can meet the requirements of production.
In summary, 35CrMo steel is an excellent alloy structural steel with good comprehensive mechanical properties, high static strength and excellent fatigue strength. It can meet the needs of various industrial enterprises for the manufacture of high-load parts and wear-resistant parts. It is the ideal choice for many fields.
