What is the BBNSteel company 09cuptire-a weathering steel main products

In recent years, in line with the development trend of iron and 09CUPTIRE-A weathering steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which 09CUPTIRE-A weathering steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their different materials and properties. According to the different uses, 09CUPTIRE-A weathering steel it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder steel and pressure vessel steel, pipeline steel, etc.

Q235NH corrosion-resistant steel plate full name: atmospheric corrosion-resistant hot continuous rolled steel, also known as Corden steel, widely used in: containers, power plants, chimney and railway engineering, such as large outdoor sculpture steel. The corrosion-resistant steel plate (i.e. atmospheric corrosion resistant steel) is a low-alloy steel series with low price and good quality, which is between ordinary steel such as 09CUPTIRE-A weathering steel and stainless steel. The corrosion-resistant steel can be continuously developed and innovated after being integrated into modern metallurgical new mechanism, new technology and new process. It is one of the series of steel with world advanced super steel technology.

The performance of heat treatment process reflects the difficulty of heat treatment and the tendency of defects of the steel. It mainly includes hardenability, superheat sensitivity, temper embrittlement tendency and oxidation decarburization tendency. The hardenability of 09CUPTIRE-A weathering steel, alloy steel is high. The cooling method can be used slowly during quenching, which can reduce the deformation and cracking tendency of the workpiece. The addition of Mn and Si will increase the superheat sensitivity of steel. The strengthening effect of alloy elements on steel in quenching and tempering state is the most significant.

S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. 09CUPTIRE-A weathering steel, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.

We have a professional production team and high-quality production equipment, and we also have a great 09CUPTIRE-A weathering steel advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the 09CUPTIRE-A weathering steel production of high-quality steel plates, steel pipes and other products that meet customer requirements.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel 09CUPTIRE-A weathering steel products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
