These percentages exist in 303, 304 and 305 series stainless steels so 18 8 is used at times to designate any and all of those alloy groups. 18 8 stainless steel offers good corrosion resistance and machines easily but will over time stain in coastal environments. They are also acceptable for use in ACQ pressure
