Q550NH weather resistant steel sheet, API 5L X60 steel plate is one mainly of Steel for large diameter pipes, API-X60 steel for the manufacture of buried pipelines for transporting natural gas can succumb to severe degradation due to corrosion by the soil through. The types of corrosion of steel that can be produced are often general corrosion and pitting.

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. Q550NH weather resistant steel sheet, 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.
