The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep EN S355ML steel processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and EN S355ML steel steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

Our pipeline products adopt the national standard and the international standard API 5L, which can meet the needs of EN S355ML steel pipelines working in different environments-on land in the open air and offshore deep water. Acid-resistant pipelines are produced for transporting highly acidic crude oil.

Weather resistant steel, as a new generation of advanced steel materials, has atmospheric corrosion resistance 2 to 5 times that of ordinary carbon steel. The longer it is used, the more prominent the corrosion resistance. Because it has the characteristics of rust resistance, no coating, thinning and consumption reduction, labor saving and energy saving, weather resistant steel can be applied to steel structures used in buildings, vehicles, bridges, towers and other long-term exposure to the atmosphere, EN S355ML steel and can also be used to manufacture containers and railway Structural components such as vehicles, oil derricks, seaport buildings, and oil platforms.

Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce EN S355ML steel, hot-rolled seamless steel tube by continuous rolling mill.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. EN S355ML steel, 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

We are the professional Chinese steel plate, steel pipe supplier. If you need any steel plate, steel pipe, we can put the steel plate, steel pipe order to our steel mill directly or collect these goods from our stock directly if we have enough ex-stock. Besides. if you need any EN S355ML steel offer or if you want to know the price and any other information about steel plate, steel pipe price, please be free to contact us.
