What is the scope of geometric dimension of Q295GNH atmospheric corrosion resisting steel

The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing Q295GNH atmospheric corrosion resisting steel high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.

Carbon steel SA516Gr70 corresponding material is SA516 Gr485 steel. SA516 Gr485 is called according to the min. tensile strength 485MPa. Our company can supply Q295GNH atmospheric corrosion resisting steel, ASME SA516Gr70 carbon steel plate and sheet with thickness ranging from 5mm to 150mm. SA516Gr70 steel plate for pressure vessels and boiler is delivered in hot rolling, controlled rolling, normalizing, while plate thickness greater than 40mm must be normalizing.

The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, Q295GNH atmospheric corrosion resisting steel, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.

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, Q295GNH atmospheric corrosion resisting steel, and greatly improves the steel material's resistance to atmospheric corrosion.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of Q295GNH atmospheric corrosion resisting steel, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
