raex 500 sheet material angle bars
The company breaks through the production limit of ultra-wide pressure vessel steel plates and can provide ultra-wide CrMo steel plates for pressure vessels over 5 meters. This breakthrough not only upgrades the manufacturing capacity of ultra-wide raex 500 sheet material steel plates, but also greatly improves the safety of petrochemical refining pipelines, promotes the development of petrochemical industry equipment, and promotes the high-end manufacturing of ultra-wide pressure vessel CrMo steel plates.
Since the foundation of the company, the Spring Festival Gala is an annual activity held at the end of the year. Now it is a part of the BBN company culture to enrich the employee's life. The annual Spring Festival Gala in 2019 was held on January 20, 2020. There are opening ceremony, leader's speech, BBN steel performance, awards for outstanding employees, lucky draw, party game, curtain call, company group photo, annual Gala dinner and other links.
raex 500 sheet material surface cracks refer to the linear cracks on the surface of raex 500 sheet material, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: raex 500 sheet material surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
"In year 2014, we participate Bangladesh national railway tender for steel plate making train carriage. We finally got the order 1000 tons and it took us 40 days to produce all the plates. The client gave very high comments to our service and raex 500 sheet material product quality.In year 2015, we won another tender for 1200 tons B480GNQR steel coils in Bangladesh, which you can find in the steel coil part."
Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our raex 500 sheet material products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
As for the mechanical properties of raex 500 sheet material, ASTM A572 Gr.50, 345 Mpa is the yield point levels most closely approximating a geometric progression pattern between 36 ksi min yield point steels covered by Specification A36/A36M and 100ksi min yield point steels covered by Specification A514/A514M.
Chromium element (Cr element) can improve the strength and hardness of raex 500 sheet material, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
In order to better develop the international steel market and make the steel products trade more prosperous at home and abroad, the company has a number of professional talents who love their posts and are proficient in their business. The company has always been adhering to the "service first, reputation first, customer first, make friends" business purpose, is willing to work together with domestic and foreign customers!
