How important is the leveling process to S420ML steel tubing

Recently, a symposium on the celebration of the 70th anniversary of the founding of the People's Republic of China by the iron and steel industry was held in Beijing Convention Center. The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, BBN S420ML steel tubing Steel Staff sang songs to the mark the 70th victory anniversary. In the last of September, Henan BBN Steel organized all employees to sing ""My Country and I"" and made a film.

The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality S420ML steel tubing products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the S420ML steel tubing steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.

Steel transportation because of the special material of S420ML steel tubing steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.

EN10025-6 S460QL structural steel plates are European standard low alloy high strength steel materials. S420ML steel tubing, S460QL steel plates are mainly used for building and engineering structures, such as plant structure, body steel frame components of bulldozers, loaders etc. all kinds of construction machinery, bridges, ships and so on.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s S420ML steel tubing domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel S420ML steel tubing products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
