What is the scope of geometric dimension of 9CuPCrNi-A steel flat bar

The 9CuPCrNi-A steel flat bar plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The 9CuPCrNi-A steel flat bar products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between 9CuPCrNi-A steel flat bar, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.

Specification range of available steel 9CuPCrNi-A steel flat bar: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates 9CuPCrNi-A steel flat bar can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.

Our 9CuPCrNi-A steel flat bar, hot rolled mild steel sheets offer excellent corrosion resistance property in the server’s environments. The mild steel sheets provide high resistance to nitric and chloride corrosion in sulfide solutions. These SA283 GrC carbon stel plates offer high strength, tensile, yield, mechanical strength, ductility, hardness, toughness, etc. Mild steel sheet is worked very easily in a high-temperature application and show excellent resistance to chloride crossing and cracking stress.

9CuPCrNi-A steel flat bar, P355GH steel yield strength in different thickness has different values.Thickness 8-16mm: 355MPa min., ＞16-40mm: 345MPa min., ＞40-60mm: 335MPa min., ＞60-100mm: 315MPa min., ＞100-150mm: 295MPa min., ＞150-250mm: 280MPa min. The elongation minimum is 20%. P355GH plate under EN10028-2:2003 standard is a pressure vessel steel. It is always delivered in hot rolling, controlled rolling, normalizing.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled 9CuPCrNi-A steel flat bar plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive 9CuPCrNi-A steel flat bar industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
