Every material selection decision includes tradeoffs. Performance can come at a price. But there is little sense in paying for capabilities that are not needed. The following suggests a framework for selecting one of a family of corrosion-resistant materials from another.
Cost is rarely ignored, so it is helpful to compare certain corrosion-resistant alloys as multiples of cost of a generally recognized standard material, in this case 304 stainless. This analysis attempts to capture all-in cost including processing, and not just per-pound acquisition cost.
