Stainless Steels Stainless steel is another example of a metal that does not rust. Through it is important to note that some grades are more resistant to rust than others. Austenitic stainless steels such as 304 or 316 have high amounts of nickel and chromium.May 29, 2018

Stainless steel Stainless steels containing high enough chromium levels do not rust, as the chromium will oxidise far quicker than iron, creating a chromium oxide layer and preventing the formation of rust. The addition of nickel further enhances a stainless steel alloys rust-proof qualities.
Which is better SS 304 or 316?
Though the stainless steel 304 alloy has a higher melting point, grade 316 has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior.
What is the most corrosive resistant element?
Iridium is the most corrosion-resistant metal known: it is not attacked by almost any acid, aqua regia, molten metals, or silicates at high temperatures.
