Keeping stainless steels stainless - The Fabricator
Stainless steel's corrosion resistance is due to a thin, chromium-rich, transparent oxide film on the surface1. This protective film develops when more than 10.5 percent of chromium is present in the alloy and when the gas or liquid environment the stainless steel is exposed to provides oxygen to its surface. Under these conditions, the surface is passive, or resistant to corrosion. Failure to develop and maintain this passive film renders the surface active, or possessing corrosion resistance similar to conventional See more on thefabricator square steel pipe spot Surface treatmentInclusions and Laminations - Rolled Alloys, Inc.Laminations are an imperfection in a steel or alloy, resulting from blisters, seams, foreign material, and/or scratches on an ingot or billet that are not repaired during the rolling process.
