S690QL machining Exporter Kuala Lumpur, Malaysia

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, S690QL machining based on a high starting point and high technology, the company has vigorously developed various steel products S690QL machining and deep-processed parts, steel structures, precision castings, seamless pipes.

Most of the S690QL machining steel materials used in industrial boilers are carbon steel materials. In a narrow sense, the boiler steel refers to the special steel used for manufacturing industrial boilers and power station boilers, mainly including pressure vessel steel, anti-oxidation steel and hot strength steel. Some of them are carbon steel, most of them are medium and low alloy steel, and a few are high alloy steel S690QL machining. In a broad sense, the boiler steel includes all the steel used to manufacture industrial boilers and utility boilers.

With the development of science, technology and industry, higher requirements are put forward for steel materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, abrasion, and other special physical and chemical properties. S690QL machining, carbon steel can no longer fully meet the requirements, so alloy steel plates appeared. Improving the strength of steel is one of the main purposes of adding alloying elements.

EN10149 S355NC steel plate/sheet,EN10149 S355NC steel plate/sheet, under EN standard, we can regard S355NC steel plate/sheet as S690QL machining high strength steels for cold-forming, normalised steel. EN10149 S355NC is mainly used as high strength steels for cold-forming,normalised steels.The EN10149 S355NC steel grade offers excellent bending,flanging cold

S690QL machining, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.

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.
