The percentage of nickel and chromium present in this grade of stainless steel provides this metal with good corrosion resistance properties, particularly to moderately caustic and acidic solutions. There are over 60 grades of stainless steel, but the entire group can be divided into just about five classes with each being identified by the alloying elements that affect their microstructure (for which they are named) and how they react with these elements.Ĭorrosionpedia Explains 18/8 Stainless Steelġ8/8 stainless steel is an outstanding metal for applications like: However, the addition of other elements, like molybdenum, nickel and nitrogen, can also play a part in this. While 18/8 steel's ability to resist corrosion-as well as its other useful properties-are enhanced by its increased chromium content. If it is damaged in any way, this film is regenerates-as long as oxygen, even in very small amounts, is present. Stainless steel's chromium content also allows the formation of a rough, corrosion-resistant chromium oxide film on the steel surface. The chromium gives the steel its stainless, corrosion-resistant properties. Stainless steel is a low-carbon steel that contains chromium at 10% or sometimes more by weight.
18/8 stainless steel may also be known as austenite steel or 304 grade steel. It's also simple to clean and available in various appearances and finishes. The numbers 18/8 represent the composition of this steel it is 18% chromium and 8% nickel, making it very resistant to corrosion and oxidation.18/8 stainless steel is also highly durable and easy to fabricate. 18/8 stainless steel is the most widely used and flexible austenitic form of stainless steel.
