Marine Grade Stainless Steel Explained - thyssenkrupp

Although molybdenum is found in some other grades of stainless steel,it is the relative high concentration (2.0 2.5%) present in 316 that helps to stop the salt water causing pitting or crevice corrosion however,it does mean that these grades are more expensive than some other grades such as 304.Images of 304 Stainless Steel in seawater imagesMarine Grade Stainless Steel Explained - thyssenkrupp Marine grade stainless steel.Stainless steelis naturally corrosion resistant however corrosion can still occur when the metal is exposed to harsh or aggressive environments such as a salt water or marine environment.What gives stainless its resistant properties is the formation of a protective chromium oxide skin on the surface of the metal,protecting the base metal (and importantly the iron present) fromHowever,304stainlesssteeldoes have one weakness,and that is it does not perform well in chlorideChloride

The chloride ion is the anion Cl.It is formed when the element chlorine gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents.Chloride salts such as sodium chloride are often very soluble in water.It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance,transmitting nerve impulses and regulating fluid in and out of cells.Less frequently,th
