B490NQR improved anti corrosion structure steel plates have better corrosion resistance than carbon steel plates in the atmosphere. With time passing by, once installed, B490NQR improved anti corrosion structure steel plates can gradually formed a protective layer of rust resistance to q bqb 340 b490nqr corten plate used in bridge engineering

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. q bqb 340 b490nqr corten plate used in bridge engineering, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 °C during heat treatment.
