Its nickname is “marine grade” for a reason. Grade 316 is similar to grade 304, but it has molybdenum as part of its chemical makeup, further increasing its corrosion resistance. The purpose of this project is to determine which metal would be the most corrosion-resistant. Similar to aluminum, copper forms a protective oxide layer when exposed to oxygen. Grade 430 stainless steel costs less than either 304 or 316, but its corrosion resistance is not high. This type … The important thing to know is that their corrosion-proof qualities are tied to their chromium content. Strength of Anodized Aluminum Anodized aluminum will flex or deflect more than steel which softens the force of impact loads. A member of the platinum group metals, iridium is white, resembling platinum, but with a slight yellowish cast. When it comes to iron and steel alloys that could be vulnerable to galvanic corrosion, zinc and aluminum-based coatings are most effective at keeping the metals safe. There are various ways of protecting metals from corrosion (oxidation) including painting, hot dip galvanizing, cathodic protection, and combinations of these. As a result, A286 alloys are great for fabrication tanks, valves, piping, heat exchangers, and other processing equipment.
