ST52 steel come under the DIN 2391 specification, it belongs to a standard structural steel grade.. ST52 grade steel is a readily weldable low carbon manganese steel with good impact resistance. The steel has excellent weldability and machinability that is similar to mild grades of steel. The steel modules are commonly seen in the construction of bridges, buildings, general engineering, etc. And it works well in extreme and cryogenic temperatures. The steel has good impact resistance and is commonly supplied in the standard normalized condition.
