While stainless steel is known for being corrosion-resistant, when its paired with other elements, it can respond differently when exposed to corrosive environments. Thats why stainless steel comes in different grades to protect itself given the application. Here are the ways stainless steel can be threatened by corrosion. Austenitic Stainless Steels Stainless Steel TypesAustenitic Stainless Steel Grades. Austenitic stainless steels are classified in the 200 and 300 series, with 16% to 30% chromium and 2% to 20% nickel for enhanced surface quality, formability, increased corrosion and wear resistance. Austenitic stainless steels are non-hardenable by heat treating.

Stainless steel's corrosion resistance depends on the formation of a "passive" chromium oxide film on the metal surface which is highly resistant to corrosion. In grades 304 and 316, about 18% of chromium is added to generate this film and, in 316, 2% molybdenum Corrosion Resistance of Stainless SteelsCorrosion resistance of stainless steels Corrosion in concrete (corrosion problems are not limited to outside surfaces !) Stainless steel provides both strength and corrosion resistance inside the concrete, providing a long, maintenance-free service life of the structure. Corrosion of unprotected carbon steel occurs even inside reinforced
In all stainless steels, chromium and nickel are critical for corrosion resistance and ductility. The addition of >10% chromium transforms steel into stainless steel, creating an adherent and invisible oxide layer that is chromium-rich. This oxide layer forms Corrosion Resistant Stainless Steel Tube - China Guanyu The corrosion resistance of a stainless steel is dependent on the presence of a protective oxide layer on its surface, but it is possible under certain conditions for this oxide layer to break down, for example in reducing acids, or in some types of combustion where the atmosphere is reducing.

Stainless steel must have at least 10.5% chromium in order for the passive layer to form. The more chromium that is added, the more stable the passive layer becomes, and the better the corrosion resistance. Other elements such as nickel, manganese, and molybdenum can be added to enhance stainless steel corrosion resistance. [ Corrosion ] Increasing the corrosion resistance of on corrosion resistance.
