What industries need 09CuPCrNi-B equivalent
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the 09CUPCRNI-B equivalent steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
ASTM Corten B steel is a hot-rolled structural steel product with better atmospheric corrosion resistance under Technical delivery conditions. ASTM Corten B steel conforms to ASTM standard, with yield strength of 355MPa and 345mpa, and the 09CUPCRNI-B equivalent yield strength depends on the thickness. The tensile strength of ASTM Corten B steel is 470-630 MPa.
In addition, according to customs statistics, from January to February, 7.81 million tons of 09CUPCRNI-B equivalent and so on steel were exported, 2.04 million tons of imported steel, and 6.01 million tons of net exported steel were converted into crude steel, a year-on-year decrease of 33.7%. According to the above data, the average daily supply of crude steel in China from January to February was 2478200 tons, down 5.09% from December of last year, up 3.70% year on year. Compared with the situation of delayed demand, steel production keeps growing, and the market presents a situation of supply exceeding demand.
