What is stainless steel?

Stainless steel stains less easily than other iron-based metals, but it’s not literally “stainless”. Just like standard steel, stainless can get marked up by fingerprints and grease, discolor, and eventually rust. The difference is resilience. Stainless steel can withstand much more time and abuse before showing signs of wear.

There are multiple grades called stainless steel, each with slightly different alloy composition, and therefore slightly different physical characteristics.

What about 316 stainless steel?

316 grade is the second-most common form of stainless steel. It has almost the same physical and mechanical properties as 304 stainless steel, and contains a similar material make-up. The key difference is that 316 stainless steel incorporates about 2 to 3 percent molybdenum. The addition increases corrosion resistance, particularly against chlorides and other industrial solvents.

Alternative 300-series grades can contain up to 7 percent molybdenum. They provide even better chloride resistance, but such heavy-duty resistance is only necessary in industrial or high concentration exposure conditions.
