This standard ASME SA516 is mainly used to improve the notch toughness important for welding steel plates for pressure vessels. The tensile strength of SA516Gr.60 (HIC) is 415MPa min. The main element content is C Mn Si, P and S control determines its performance. SA516Gr.60 (HIC) chemical composition: C: ≤0.30, Mn: 0.79-1.30, P: ≤0.035, S: ≤0.035, Si: 0.13-0.45. It is a carbon steel material for medium and low temperature pressure vessels.

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, acier S690QL equivalent and can also be used to manufacture containers and railway Structural components such as vehicles, oil derricks, seaport buildings, and oil platforms.

X42 steel plate/pipes, API 5L X42 steel plate/pipes, under API 5L standard, we can regard acier S690QL equivalent pipe, X42 steel plate/pipes as large diameter pipes. X42 steel plate/pipes is one mainly of Steel for large diameter pipes, API-X42 steel used for pressure liquid transport, oil, gas, water and other liquid transportation, oilfield engineering, ductwork, construction, steel pipe and oil and gas project which use pipes.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 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. acier S690QL equivalent, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
