Stainless Steel

From Applied Energy Systems, Inc.
 

 

Anyone who lives by the ocean knows that stainless steel is not stain proof but just what it says, it stains less. In the presence of a strong chloride ion (found in the air by the ocean) the iron in stainless steel can be freed to react with oxygen to form small rust or pits in the surface. All stainless steels are by definition iron based alloys. Primary alloying elements are nickel and chromium. A number of these alloys can be autogenously welded successfully. Stainless steel 316L is the alloy of preference for high purity tubing. It is an alloy that is very weldable and can be electropolished to provide a chemically inert surface. Electropolishing removes the free iron in the surface resulting in a chrome rich and inert layer.
