EN10028-6 P690QL1 steel for larger storage tanks

EN10028-6 P690QL1 material is a quenched and tempered weldable fine-grained steel and alloy steel. It is also steel for pressure equipment, with good plasticity, toughness, cold bending performance and welding performance.

The minimum yield strength of the container steel plate is 690MPa, and the tensile strength is 770-940MPa. With the enlargement of pressure vessels, the application demand for high-strength steel is increasing. With the market demand for larger storage tanks, higher requirements are put forward on the strength of the steel plates used. The application of high-strength steel plates, It can reduce the quality of storage tank products and achieve greater product volume.

Application scope:
P690QL1 pressure vessel steel plate is widely used in petroleum, chemical, power station, boiler and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums , Liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, turbine volutes and other equipment and components. P690QL1 steel plates can be produced z15-z35 various grades of anti-lamellar tearing (thickness direction performance) steel plates.
