St37-2 carbon structural steel
ST37-2 is a kind of ordinary structural steel, which is used in construction and underground engineering.
ST37-2 is a grade of carbon structural steel material in Germany. This material corresponds to my country's equivalent to carbon structural steel Q235B (the old grade is: A3-B). In addition, because this steel and my country's high-quality carbon structural steel 20 steel is also similar, and it is also replaced by 20 steel.
