What are the main components of S355ML Z35

The advantages of S355ML Z35, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.

On the morning of March 10th, according to the news conference of the Joint Prevention and Control Mechanism of the State Council, Deputy Director of the Emergency Management Department Shang Yong said that since the outbreak, 20,000 and 172,000 safety guidance groups have been organized nationwide, keeping a close eye on High-risk industries such as coal mines and non-coal mines inspected and guided 223,000 enterprises and rectified 168,000 hidden problems.

Low alloy coils are steel coils made of steel with a low alloy content, usually less than 3.5%. Low alloy coil materials mainly include A572 Gr 50, S355JR, SS490, ST52-3, Q345B, etc.. These grades are also the most widely used and produced low-alloy high-strength steel grades in the world. The strength of low alloy coils is about 20% to 30% higher than that of ordinary carbon structural steel, S355ML Z35. And the atmospheric corrosion resistance of low alloy coils is 20% to 38% higher than that of ordinary carbon structural steel.
