Surface quality of 09CuPCrNi-A hot rolled sheets

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for 09CuPCrNi-A hot rolled sheets various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several 09CuPCrNi-A hot rolled sheets after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

Structural steel S355JR, S355J0, S355J2G, S355J2G4 are low-alloy high-strength structural steels that comply with the European standard EN10025. S355JR steel in China is a low-alloy high-strength structural steel with a hardness of 70-80B and a yield strength of 300-400MPa. S355J2G3 steel is roughly equivalent to GB Q345D. S355J2G3 means that the delivery state is normalized, and the impact energy at -20°C is 27J. G3 and G4 mean the deoxidation method.

There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than 09CuPCrNi-A hot rolled sheets, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.

ST37-2 is a kind of low carbon steel with carbon content of 0.20%, similar to S235JR or Q235 09CuPCrNi-A hot rolled sheets. It's not as strong as common ASTM A36, but it is also widely applied by everyday uses and structural applications where high strength is not so important. Equal ST37-2 angle steel size: 09CuPCrNi-A hot rolled sheets Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 - 35 mm. Length: 6 m, 9 m or as required. Unequal ST37-2 angle steel size: 09CuPCrNi-A hot rolled sheets Size: 30 × 20 mm to 250 × 90 mm. Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.

BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.
