Q BQB310 QStE380TM steel work / steel structure / steel machining parts

Q BQB310 QStE380TM steel is defined under Q/BQB310 standard. We can regard QStE380TM steel work as high yield strength steels for cold-forming.

QStE380TM steel work / steel structure / steel machining parts are made of steel QStE380TM raw material. QStE380TM steel work widely used in the structure parts that require high strength and good cold formability, such as truck beams, Housing beam.
