Effect of cooling process on microstructure and properties of 09CuPCrNi-B steel properties

Steel plates for high-rise buildings have the properties of easy welding, earthquake resistance, and low-temperature impact resistance, and are mainly used in large-scale projects such as high-rise buildings, super-tall buildings, large-span stadiums, airports, exhibition centers, and steel structure workshops. Compared with ordinary Q235B / Q345B steel plates, these plates 09CUPCRNI-B steel properties for high-rise buildings have upper limits on yield strength and improved tensile strength, and have requirements for carbon equivalent and yield ratio indexes.

The advantages of flame cutting are simple cutting and low cost. The disadvantage of flame cutting is that when cutting thin plates, cutting deformation problems are prone to occur, and the materials that can be cut have certain limitations. The advantage of CNC cutting is that it can cut 09CUPCRNI-B steel properties and any complex parts with high cutting accuracy. The disadvantage of CNC cutting is that there are certain operational and technical requirements.

The company focuses on quality building, continuously create greatest value for customers, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, perfect sales services, strict quality purchase management system and science overall marketing means. We are willing to go hand in hand with you for common development. To be the best service provider for iron & steel products globally is our goal.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate 09CUPCRNI-B steel properties EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
