09CuPCrNi-A steel belongs to weathering steel. Through alloying of Cu, Mn, Si, Al and simply adjusting part of element content of ordinary low carbon steel (Q235 steel), economic weathering steel with good atmospheric corrosion resistance and comprehensive mechanical properties can be produced without changing the production process of Q235 steel. 09CuPCrNi-A steel is mainly used for railway, vehicle, bridge, tower and other steel structures exposed to the atmosphere for a long time.
Weathering steel plate is a kind of natural weathering steel plate with atmospheric corrosion resistance, characteristic corrosion and oxidation, which has been obtained in many fields. The common basic properties and the state of various weathering steel plates have been well reflected in the construction. At present, it is mainly used for welding and manufacturing of traffic vehicles, construction machinery, bridges, towers, containers, steel containers and other low alloy structural steel. Features: strong toughness, rust resistance, corrosion resistance, thinning and consumption reduction, energy saving.
Q355GNHE corten steel is characterized by adding a small amount of Cu, P, Cr, Ni and other alloying elements to the steel, so that the steel material forms a dense layer between the rust layer and the substrate with a thickness of about 50 to 100 μm and good adhesion to the substrate metal The amorphous spinel oxide layer prevents oxygen and water in the atmosphere from penetrating into the steel substrate, slows down the rust development to the steel material, and greatly improves the steel material's resistance to atmospheric corrosion,A709 grade 50 bridge steel plate.
A709 grade 50 bridge steel plate,As to the Chemical composition, the different content is a main on carbon content, while the carbon content of A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 grade D is 230MPa (33 ksi).A709 grade 50 bridge steel plate
We have our own factory, including the production and manufacturing of steel pipes, with a special steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect after-sale service guarantee system, lets the customer save the worry and the labor.
The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
