How strong is 09CuPTiRE-B specification?

Chinese iron ore and steel prices recovered on Thursday after easing on the first 09CuPTiRE-B specification trading day of the year, but doubts remain over the sustainability of such gains amid concerns over growth in the world’s second-largest economy. The rebound followed news that China’s state planner has approved inter-city railway projects in the eastern provinces of Jiangsu and Anhui, with a combined total investment value of .7 billion. The most-active rebar contract on the Shanghai Futures Exchange ended the session up nearly 2 percent at 3,455 yuan (2.48) a tonne. Hot rolled 09CuPTiRE-B specification coil climbed 1.3 percent to 3,350 yuan.Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, 09CuPTiRE-B specification weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. 09CuPTiRE-B specification, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
