What is 18/8 Stainless Steel? - Definition from Corrosionpedia

18/8 stainless steel is 304 grade stainless steel,which is the most widely used and flexible austenitic form of stainless steel.The numbers 18/8 represent the composition of this steel as 18% chromium and 8% nickel,making it very resistant to corrosion and oxidation.18/8 stainless steel is also highly durable and can be fabricated with ease.Welding of austenitic stainless steels for cryogenic LNG Sometimes for large storage tank construction.Piping in critical applications.36NiFe Low expansion 36 % Ni-Fe alloy Piping; Small vessels.Sometimes for large storage tanks 304 L Stainless steel type AISI 304 L 9 Ni 9 % Ni Steel Storage tanks Figure 2 TypicalWelded Steel Tank Manufacturer CST IndustriesUnlike field welded and painted tanks,CST welded steel tanks are fabricated in a modern,indoor,controlled environment.Once fabricated the tank is cleaned,coated and cured in our oven on a specially designed,controlled processing line.In addition to factory coated steel tanks,CST fabricates tanks from stainless steel and aluminum.
