SAE52100 Precision Steel Pipe is a kind of high carbon chromium bearing steel with low alloy content, good performance and Mainly used for manufacturing steel balls, rollers, and shaft sleeves on transmission shafts of internal combustion engines, electric locomotives, machine tools, tractors, steel rolling equipment, drilling machines, railway vehicles, and mining machinery.
Inquiry nowThe comprehensive performance of SAE52100 bearing steel pipe is good. After quenching and tempering, the hardness is high and uniform, and the wear resistance and anti fatigue strength are high. Good heat workability. After spheroidization annealing, it has good processability, but is sensitive to the formation of white spots. Mainly used for manufacturing steel balls, rollers, and shaft sleeves on transmission shafts of internal combustion engines, electric locomotives, machine tools, tractors, steel rolling equipment, drilling machines, railway vehicles, and mining machinery.
