(1) corrosion resistant steel 20MnSiCrV in the pH value of 12.8 saturated Ca (OH) 2 solution in the Cl-corrosion resistance of ordinary steel is 20MnSiV 1.5 times. Compared with ordinary steel, corrosion resistance steel bar showed good corrosion resistance, salt spray test corrosion rate of 58% of ordinary steel, corrosion pit depth of 74% of ordinary steel.high garde aisi 304 stainless steel tube coil (2) The corrosion sensitivity of the corrosion-resistant steel bar is greatly reduced by the addition of alloying element, but the corrosion sensitivity is still increasing with the prolongation of corrosion time in the chloride environment.4*8ft stainless steel sheet price per sheet 304 (3) The rust layer of ordinary reinforced salt spray has a single layer structure, and the rust layer of corrosion resistant steel is a double layer structure, and Cr and Si appear in its rust layer enrichment, which helps to form a dense inner Rust layer.40 мс размер трубы оцинкованная стальная труба
