Common Forms of Testing—and Their Applications. Although corrosion can be detrimental to the service life of many stainless steels and related alloys, there are, fortunately, many methods with which to help predict a material's expected performance. The American Society for Testing Methods has standardized many of these methods and are, therefore, part of the standard toolkit with which one can help to minimize the costly effects of corrosion in metals. 518
