Compared with carbon steel, ASTM A588 Grade K weathering steel has better corrosion resistance in the atmosphere. Compared to stainless steel, ASTM A588 Grade K only trace amounts of alloying elements, the alloy elements of total weathering steel such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and other only a few percent, rather than as stainless steel, reached a hundred per dozen, so the price is relatively cheap.
