The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. A573 Gr 70 CS steel carbon plate, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.
A573 Gr 70 CS steel carbon plate, Stainless steel relies on a very thin, solid, fine and stable chromium rich oxide film (protective film) formed on its surface to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the ability of corrosion resistance. Once the film is damaged for some reason, the oxygen atoms in the air or liquid will continuously penetrate or the iron atoms in the metal will continuously separate, forming loose iron oxide, and the metal surface will be continuously rusted.
Our A573 Gr 70 CS steel carbon plate pipeline steel has once again helped the construction of the China-Russia East Line Natural Gas Pipeline. During 2017 - 2018, the company successively supplied more than 10,000 tons of high-grade pipeline steel materials for the northern section of the Sino-Russian Eastern Gas Pipeline project, helping the northern section of the A573 Gr 70 CS steel carbon plate project to be successfully completed. Now we reload the task and will provide API 5L X80 high-grade pipeline steel for the middle section of the China-Russia Eastern Gas Pipeline project.
Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.
The European steel industry has been hit hard by the coronavirus pandemic. The auto industry, the second largest consumer of A573 Gr 70 CS steel carbon plate and so on steel, was temporarily shut down, while construction, the biggest consumer, slowed sharply in the UK in the last week of March, experts reported. It can be expected that the current crisis (which is still intensifying) will have the same or even greater impact on the steel industry as the global financial crisis.
