05CuPCrNi steel pipe surface quality inspection

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, 05CUPCRNI steel pipe quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the 05CUPCRNI steel pipe International leading steel materials supplier.

The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, 05CUPCRNI steel pipe steel structures and oil tank projects. Seeking new developments in new technology and business areas, and fostering a large number of industry-leading, international-level projects.

Strip steel is mainly used for the manufacture of welded pipes, clamps, washers, spring blades, saw blades, blades and other fields, so the 05CUPCRNI steel pipe, strip steel specifications are also relatively standardized. First, the strip width should be within 1300mm, if it is too wide, it will become a steel plate, and the machining is not allowed to be too wide, otherwise it will fail. Second, the strip steel length is not limited, and the strip steel can be coiled together after bending, reducing most of the space.

Weathering steel plate refers to the low alloy structural steel with protective rust layer and atmospheric corrosion resistance, which can be used to manufacture steel structures such as vehicles, bridges, towers, containers, etc. Compared with 05CUPCRNI steel pipe, ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only a small amount of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and so on. The total amount of alloy elements only accounts for a few percent, instead of more than 10 percent as stainless steel, so the weathering steel price is relatively low.

05CUPCRNI steel pipe, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, 05CUPCRNI steel pipe sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
