AISI 5140 steel 1.7035 structural alloy steel
Description
5140 steel has good comprehensive mechanical properties and is one of the most widely used steel types, used for manufacturing parts of medium speed and medium load, such as machine tool gear, shaft, worm, spline shaft and so on. The tensile strength, yield strength and hardenability of 5140 alloy steel are higher than 1045 steel, with higher fatigue strength and good toughness, normalizing or tempering machinability are very good, annealing machinability is also good, generally used after tempering treatment.
Otai special steel is AISI 5140 Alloy steel stockholders and suppliers from China.
