3 or 4-4inch 1-2inch-2inch 90r elbows malleable cast iron steel pipe fitting hot dipped fittings

Stainless steel does not rust because Cr and Fe in it are oxidized to form a dense passive film to prevent further corrosion.
AISI 304 stainless steel has excellent corrosion resistance in mild atmosphere and fresh water, and even the surface will not rust. But it is not resistant to halide (such as chloride, fluoride, etc.) corrosion, because halide easily penetrates the passive film, making stainless steel lose its resistance.
