GB Q235NH Chinese steel grade,Pipeline steel refers to the hot rolled coil plate or wide thick plate used to transport oil, natural gas and other large-diameter welded steel pipes. In the process of using pipeline steel, it is required not only to have high compressive strength, but also to have high low temperature toughness and excellent welding performance. Pipeline steel plates are used to make oil and gas pipelines. The main pipeline steel grades are API 5L grade B, API 5L X42, API 5L X60, API 5L X65 and so on.GB Q235NH Chinese steel grade

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.GB Q235NH Chinese steel grade

Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

SA516Gr70 steel chemical composition (%):C≤030, Mn: 079-130, P≤0035, S: ≤0035, Si: 013-045 ASME SA516Gr70 material is a carbon steel grade for medium and low temperature pressure vessels In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ SA516Gr70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels,GB Q235NH Chinese steel grade.
