17MN4 steel plate, Q235NH weathering steel, DIN 17135 17MN4 steel plate is a kind of material for boiler and pressure vessel steel. DIN 17135 17MN4 steel plate is characterized by a minimum yield strength of 220 - 295 MPa and by good weldability, so 17MN4 steel is mainly used for manufacturing boilers, pressure vessels and pipes transporting hot liquids.

DIN 17102 TStE355 is mainly used for grain structure steel and normal rolling steel. Tste355 steel plate is a kind of grain structure steel. It is a standard rolled steel plate / sheet specially manufactured for different types of welding structures. It is made of basic materials, with high temperature resistance and low temperature resistance. Product Q235NH weathering steel is suitable for pressure boiler, mobile and vertical storage tank, high pressure pipeline, bridge, mast, cable, etc.

Composition characteristics of low alloy structural steel, Q235NH weathering steel: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.

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. Q235NH weathering steel, 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.
