BBN steel make efforts to reduce cost of Q310NQL2 atmospheric corrosion resistant structural steel

Our company has sales department, technology department, quality inspection department, after-sales department, logistics department. Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.

904L corrosion-resistant steel is developed with various sulfuric acid corrosion applications. 904L corrosion-resistant steel has high chromium content and enough nickel content. The addition of copper makes 904L corrosion-resistant steel have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking, and its pitting corrosion resistance is slightly better than other steels, such as Q310NQL2 atmospheric corrosion resistant structural steel.

Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel Q310NQL2 atmospheric corrosion resistant structural steel. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure a good cutting effect. The CNC flame cutting machine is a mechanical equipment mainly suitable for the cutting of medium and thick plates. Compared with other similar thermal cutting methods, the CNC flame cutting machine has the characteristics of high cutting quality, good cutting surface perpendicularity, and large cutting thickness.

In 2016. Our company offer 1200 tons API 5L GR.B hot rolled coil to Bangladesh——100 tons for 3.9*625mm, and 1100 tons for 7*683mm. It is one tender project, we get the tender at the end of 2015, and arrange the production in 2016. They required the tolerance of thickness is +0.1/-0.2mm, and width tolerance is +/-0.5mm, which is a very high requirement for coil tolerance, but our mill handling this very well. and our Q/C department witness all of the process.
