The steel used for bridge beams should also have excellent welding function and low notch sensitivity, high strength, toughness, and load and impact from rolling stock, as well as outstanding fatigue resistance, certain low temperature resistance, and atmospheric corrosion resistance. Q460qC steel plate delivery status: S355J0WP weathering steel plate steel products are delivered in hot rolled, controlled rolled or normalized conditions.

Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.

Most common S355J0WP weathering steel plate steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled S355J0WP weathering steel plate steel plates.
