P690Q steel boiler plate
P690Q Boiler Steel Plate Products Description
P690Q pvq steel plate is a quenched and tempered weldable fine grain steel, which belongs to high strength low alloy steel and implements European standard EN 10028-6. P690Q pressure vessel steel has good toughness and plasticity, and can maintain impact toughness in low temperature environment.
In addition, P690Q boiler quality plate also has good plasticity and cold bending performance, as well as certain corrosion resistance and good dimensional stability. At the same time, the fatigue resistance of P690Q pressure vessel quality steel can maintain stable performance during long-term use.
P690Q hot rolled boiler steel plate is widely used in petroleum, chemical, power station, boiler and other industries; P690Q is used to manufacture reactors, heat exchangers, separators, spherical tanks and other equipment and components; P690Q can also be used in construction, bridges, aerospace, ships and other fields.
