Q235NH weather resistant steel plate is currently a popular plate in building decoration engineering and product production. Generally, it refers to a plate that is resistant to corrosion and not easy to rust in weak corrosive media such as atmosphere and
The annealing of Q295NH weathering steel plate can maintain the precise bright tube and dimensional accuracy of the Q295NH weathering steel plate, which is more and more popular with customers.
Many metal materials rust due to oxidation, and later corrosion will lead to a decline in product quality and service life. But after production, the Q355GNH weathering steel plate is all red embroidered, and a black embroidered layer will be formed on th
The following methods can be used to reduce the welding stress and deformation of ASTM CortenA weathering steel:
(1) Reverse deformation method; (2) Reasonable installation and welding sequence; (3) Rigid fixing method; (4) Heat dissipation method; (5) H
When the Q355NH weathering steel plate with a thickness of more than 10 mm is rolled in the rolling pit, after the wear-resistant liner bites into the rolling mill, the splint should be opened quickly to reduce the gap between the Q355NH weathering steel
Q355NH weathering steel is composed of the following alloy components by weight: carbon: 0.12-0.21, silicon: 0.2-2.0, manganese: 0.7-2.0, sulfur ≤0.036, phosphorus ≤0.034, copper: 0.10-0.40, aluminum:0.2, the remaining is iron and trace impurities.
We can supply the Q355NH weathering steel plate with high quality and low price. If you want to know more about Q355NH weathering steel plate, please contact us freely. Our sale person will contact you as soon as possible.
Q355NH weathering steel plate is characterized by uniform rust red color, good color fastness and adhesion, no peeling, no slag falling, no rust water flowing in the later stage, and super corrosion resistance.
After welding, cooling and shrinkage can be uniform at the same time, so as to significantly reduce the ASTM A588 Grade C weathering steel plate welding stress and welding deformation. Post-welding heat treatment of ASTM A588 Grade C weathering steel plat
Full annealing. The process of heating Q295NH steel plate to 30~50℃ above AC3, complete austenitizing, followed by slow cooling, and obtaining near equilibrium microstructure is called complete annealing. Mainly used for medium carbon carbon steel and med
