B490NQR Weathering steel tube B490NQR steel pipe Processing

B490NQR Weathering steel tube is a weather resistant steel created by alloying copper, chromium and nickel.B490NQR steel has added phosphorous which makes the material best suited for gas flue applications and for aesthetic facias . B490NQR steel is a family member of Q/BQB 340 steel.

B490NQR steel pipe improved anti corrosion structure steel tube have better corrosion resistance than carbon steel  in the atmosphere. With time passing by, once installed, B490NQR improved anti corrosion structure steel can gradually formed a protective layer of rust resistance to atmospheric corrosion.
