High strength steel is mainly used in offshore engineering, lifting equipment, construction machinery, container storage tank and other important steel structures with harsh working conditions, hoping to reduce weight. The application of S690QL steel welding, high strength steel can not only reduce material cost, transportation cost and production cost, but also save welding material consumption, welding work hour; reduce post welding stress, preheating temperature and post weld heat treatment requirements.

A335 P22 steel pipe belongs to ferrite alloy steel nominal pipe for high temperature use. Chemical composition of A335 P22 steel pipe: C 0.10-0.20, Mn 0.30-0.80, P ≤ 0.025, S ≤ 0.025, Si 0.10-0.50, Mo 0.44-0.65. Mechanical properties of A335 P22 steel pipe: tensile strength 415mpa, yield strength 205 MPa. S690QL steel welding, A335 P22 steel pipe is characterized by good process performance, less sensitivity to the heating temperature of heat treatment, good welding performance, good plasticity, and low strength, especially the high temperature rupture strength is lower than 12Cr1MoV steel. When used at the same temperature and stress, its wall thickness is about 30% thicker than 12Cr1MoV Steel.

The price of common carbon plate is relatively low compared with other kinds of steel S690QL steel welding, and it can be used in a wide range of occasions, such as construction, machinery manufacturing, etc. Therefore, carbon plate is favored by users all over the world. And because of its large demand, fast circulation, the steel suppliers and exporters would like to keep huge carbon plate stocks, and thus the delivery is very quick. We also have large quantity stock for carbon plates. And we provide further processing for the carbon plate.
