Why stainless steel also rust? When the surface of stainless steel tube appears brown rust spot (spot), people are very surprised: "stainless steel is not rusty, rust is not stainless steel, it may be a problem of steel." In fact, this is a one-sided misconception about the lack of stainless steel. Stainless steel is also rusty under certain conditions.

However, the corrosion resistance of the steel varies with its chemical composition, additive state, service condition and environmental medium type. For example, 304 steel pipes, in the dry and clean atmosphere, have excellent corrosion resistance, but move it to the seaside area, and in the sea fog containing a large amount of salt, it will soon rust; and 316 steel pipes are good. Therefore, not any stainless steel can be corroded without rust in any environment.[url=https://www.stainlesssheetsupply.com/steel-list/1780.html]Good Quality And Free Sample Hardface Flux Cored Wire[/url] Stainless steel is a thin, sturdy, stable, stable chromium oxide film (protective film) formed on its surface, which prevents the continuous infiltration and oxidation of oxygen atoms, and has the ability to resist corrosion. Once for some reason, the film is constantly destroyed, the oxygen atoms in the air or liquid are constantly infiltrated, or the iron atoms in the metal are constantly separated out to form a loose iron oxide, and the metal surface is constantly corroded.[url=https://www.stainlesssteellist.com/lista-productos/2274.html]Tubo de acero 13/8[/url]
