Welcome to BBN High Strength Steels Factory

What is the S690QL+QT EN 10025-6 high strength steel surface test

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional S690QL+QT EN 10025-6 high strength steel production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of S690QL+QT EN 10025-6 high strength steel leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

The ASTM A213 T9 alloy tubing heat exchange finned tube is the most used heat exchanger tube in the heat exchange of gas and liquid. It is to add fin to the common base tube to enhance heating, so as to achieve the fast heat transfer of heat exchanger through heat exchange finned tube. According to the type of materials S690QL+QT EN 10025-6 high strength steel , it is divided into single-metal finned tube and bimetal finned tube.

The main characteristics of S690QL+QT EN 10025-6 high strength steel, 12Cr1MoV alloy steel plate are as follows:Compared with 12CrMoV steel, 12Cr1MoV alloy steel plate has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is close to the stress rupture strength, and it has high plasticity under the condition of long-term tension. The process and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress relief treatment is required after welding.

S690QL+QT EN 10025-6 high strength steel, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.

There are a lot of ASTM standards for pressure vessel steel plates. Such as ASTM A204, A285, A302, A387, A515, A516, A517, A537, A612, A841, etc. Those ASTM steel plates have different thickness ranges. S690QL+QT EN 10025-6 high strength steel, ASTM A204 plates shall not thicker than 150mm. ASTM A285 plates shall not thicker than 50mm. ASTM A515 plates shall not thicker than 200mm. ASTM A517 plates and A537 plates shall not thicker than 150mm. ASTM A612 plates shall not thicker than 25mm. ASTM A841 plates shall not thicker than 100mm.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s S690QL+QT EN 10025-6 high strength steel 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.

Since its establishment, the company has been deeply supported and loved by customers with its unique business philosophy and business model. The company has always adhered to the tenet of "credibility first, integrity-based, quality first" and sincerely serves new and old customers. At the same time, it keeps pace with the times based on market orientation, continuously expands offline channels, and gradually establishes a complete online E-commerce business management platform. We will always promote our after-sales service to make client satisfied with our goods.
