chemical composition of 40Cr steel(%):

C: 0.37~0.44

Si: 0.17~0.37

Mn:0.50~0.80

Cr: 0.80~1.10

Ni:≤0.30

P:≤0.030

S: ≤0.030

Cu: ≤0.30

Mo:≤0.10

Application

After quenching and tempering, 40Cr steel is used to manufacture mechanical parts under medium load and medium speed, such as car steering knuckles, rear half shafts and gears, shafts, worms, spline shafts, sleeves on machine tools, etc. After quenching and tempering at medium temperature, this steel is used to manufacture parts that can withstand high loads, shocks and medium speeds, such as gears, spindles, oil pump rotors, sliders, and collars.
