(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.Hair Line 304 Stainless Steel Sheet 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.304 astm a167 304 stainless steel sheet (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.316 Ëĺíňŕ čç íĺđćŕâĺţůĺé ńňŕëč 316L
