Heat Treatment of Stainless Steels

Over a few decades various means of retarding or preven-ting corrosion of iron and steel products have been extensively used. These include painting or coating with metals or sometimes nonmetals that proved helpful in inhibiting corrosion in specific environments to which
the products would be subjected. However, paintings or coatings have limited life. They require periodic repl-acement to prevent corrosion which will eventually take place.
