St37 is a German brand, but it is a general brand, and there are several smaller brands.

For example, St37-2 St37-3U St37-3n RSt-2 USt37-2 and so on.

ST37-2 is a German carbon structural steel material grade

This material corresponds to China's equivalent carbon structural steel Q235B (old number :A3-B)

In addition: Because this steel and China's high-quality carbon structure steel 20 steel is similar, it is also useful to replace 20 steel.
