EN 10025-6 S690QL equivalent dimensional tolerance

Special-shaped seamless pipe is the general term of seamless pipe with other cross-section shapes except circular pipe. According to the different shapes and sizes of steel pipe sections, it can be divided into equal wall thickness special-shaped seamless pipe (code D), unequal wall thickness special-shaped seamless pipe (code BD), variable diameter special-shaped seamless pipe (code BJ). EN 10025-6 S690QL equivalent. Special seamless pipe is widely used in all kinds of structural parts, tools and mechanical parts. Compared with the round pipe, the special-shaped pipe has larger inertia moment and section modulus, larger bending and torsion resistance, which can greatly reduce the structure weight and save steel.

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 EN 10025-6 S690QL equivalent 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 EN 10025-6 S690QL equivalent leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This EN 10025-6 S690QL equivalent production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate EN 10025-6 S690QL equivalent size.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as EN 10025-6 S690QL equivalent. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
