ASTM A516 is also known as ASME SA516. The A516 / SA516 standard specification for pressure vessel plates, carbon steel, for moderate- and lower-temperature service. A grade ASTM A709 carbon steel plate intended primarily for service in welded pressure vessels where improved notch toughness is required, and is normally found in moderate and lower temperature applications. All plates over 1-1/2″ Thick are required to be normalized. A516 Grade 70 steel is the most popular pressure vessel grade of steel plate in the industry.
The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they ASTM A709 carbon steel plate work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.

Good news: The largest steel importer in Nigeria ordered 4068 tons API 5L X52Q PSL2 3LPE seamless pipes and also ordered 8 pcs 42699.6 m³big diameter Crude oil storage doom roof tank in A537CL2 steel grade. In Sep 2019, This Nigeria client visited our company and factory, they were very satisfied with our company's quality control,production capacity and service. We also have reached a agreement for Phase II Project, It is also with another 10,000 tons APl 5L X52Q PSL2 3LPE seamless pipes.
Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our ASTM A709 carbon steel plate products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.
