 Properties and applications 60si2mna strength, hardness. Flexibility and hardenability of steel than 65 high, with a thermal sensitivity and tendency to temper brittleness, water quenching have to cracking tendencies. Cutting can still be annealed, cold plastic deformation is low, poor welding. By the middle of the plate spring load, diameter 7-20mm of coil spring and spring washer. Spring ring. High wear parts, such as grinding spindle of spring chuck. Precision machine screw. Cutter, spiral roller bearings on the rings. Railway rail and so on. 
 60Si2MnA low content of alloying elements, than 60Si2Mn high hardenability, toughness, ductility and higher, a small tendency to decarburization, tempering good stability, thermal processing performance and low cost. 60si2mna spring steel, manganese improve hardenability, φ12mm the hardenability of steel oil can, a small surface decarburization tendency than silicon, the mechanical properties after heat treatment is better than carbon steel, but there are overheating and temper embrittlement susceptibility 
 . 60Si2MnA production instead of heavy, medium and small cars, and other medium-sized cross-section of leaf spring leaf spring and coil spring. 60si2mna strength hardness and elasticity hardenability steel is higher than 65, with a thermal sensitivity and tendency to temper brittleness, water quenching have to cracking tendencies. Cutting can still be annealed, cold plastic deformation is low, poor welding. By the middle of the plate spring load, diameter 7-20mm of coil spring and spring washer. Spring ring. High wear parts, such as grinding spindle of spring chuck. Precision machine screw. Cutter, spiral roller bearings on the rings. Railway rail and so on.

 60SiMn, 60Si2MnA, 55Si2Mn contrast 
 60SiMn, 60Si2MnA - compared with 55Si2Mn steel, strength and elastic limit are slightly higher (including steel 60Si2MnA better) good hardenability is also straight, the critical quenching in oil until about 37 ~ 73mm, the same as other properties ; main use state quenching and tempering temperature used. Uses: This steel is widely used for the manufacture of railroad cars, automobiles, tractors and other industrial manufacturers bear a greater load of ≤ 30mm diameter flat spring or spiral spring, such as cars, train cars to withstand stress and vibration with the lower spring plate, safety valve and check valve spring and the temperature on the <250 ℃ heat-resistant non-corrosive medium spring; to withstand alternating loads and work under high stress the important roll of large springs and withstand severe wear and tear of mechanical parts. 

 Our advantages: the supply and service has a long experience, has a complete inventory of steel and rich, with a regular purchase channels and reasonable price, 
 Has a good technical support and after-sales service, have a perfect logistics and speed of delivery, the Division has owned the team can provide customers with quick material delivery, remote clients are given special express delivery company. The following provincial areas can be served:
