Carbon steel pipe can be seamless or seam welded. Seamless steel pipe is a large category of steel pipe, which can include carbon seamless steel pipe, low alloy seamless steel pipe, high pressure boiler pipe, oil cracking pipe and so on.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. ZQS700L automotive steel sheet, 40Cr alloy chemical composition (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). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785

In 2015, we participated in an tender for oil and casing pipe in Pakistan. Because of our professional service and company strength. The end user chose us as the final contractor of the project of 22000 meters pipes of different sizes production. It takes us about 3 months to produce all the pipes ZQS700L automotive steel sheet .
