What is modified 09CuPCrNi-B steel standard

LNG ships are called "super-refrigerated vehicles on the sea", and their service environment is at a very low temperature of minus 163 degrees Celsius. This requires that the steel for LNG storage tanks must have low temperature resistance, often using Invar steel or 9Ni steel. At present, a complete series of nickel steels such as 0.5Ni steel, 2.5Ni steel, 3.5Ni steel, 5Ni steel, and 9Ni steel have been formed in the field of low-temperature steel. China has also developed relatively mature 3.5Ni steel and 5Ni steel. And 9Ni steel, and successfully used in the construction of low-temperature transport ships.According to the type of production, boiler tubes can be divided into seamless steel tubes and welded steel tubes. Boiler tubes are mainly used in pipelines, heating equipment, machinery industry, petroleum geological exploration, chemical industry and other fields. Because of the special purpose of the boiler tubes, the technical parameter requirements of the 09CUPCRNI-B steel standard, boiler tubes are also different. Generally speaking, boiler tubes must have pressure resistance, high temperature resistance, oxidation and corrosion resistance, and high tensile strength.Online sale hot rolled plate 3000 tons 09CUPCRNI-B steel standard in Tianjin city50*2180*10000, 50*2500*12000, 50*2460*9250, 50*2440*9450, 50*2200*12003, 50*2200*12000, 50*2200*12004, 50*2430*7600, 50*2440*4200, 70*1620*7400, 50*2440*14200, 60*2500*7700, 50*2380*11400, 60*2500*10100, 66*2920*11000, 75*2000*8750, 50*2430*7700, 50*2200*11850, 70*1600*6000, 89*2600*6650, 50*2300*11600, 70*2920*8400, 100*2220*3050, 105*2560*7040.The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
