Start with the coarsest 60-grit abrasive and proceed using finer versions 180-grit, 320-grit, and lastly 400-grit. The main difference between 304 and 316 stainless steel is 316 SS has the addition of molybdenum. The carbon percentage can range from 0.03% to 1.2%. In addition, 18-8 stainless steel is a stainless steel grade from the 300 series or is regarded as the Austenitic stainless steel. 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. Other screen manufacturers use Grade 304, which is a cheaper mesh offering some corrosion resistance, but simply doesn't compare to Marine Grade 316, which provides superior resistance to a wider range of corrosive medias. Stainless steel is an alloy of iron that is resistant to rusting and corrosion.It contains at least 19% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. 304 stainless steel is the best type of steel to use for a grill, as it has the highest chromium and nickel content.
