Stainless steels are widely and effectively joined by a variety of welding techniques. There are, however, many different stainless steels, and techniques to produce quality welds differ among the types of alloys. Stainless steels are ferrous alloys containing a minimum of 10% chromium, required to produce the resistance to atmospheric corrosion that is associated with these alloys. Other alloys elements can be added to confer specific properties. There are scores of standard stainless steels, and many more property grades. These numerous types of alloys are classified into four categories based on their crystalline structure. Before addressing the welding procedures of stainless steels, features of these classes need to be described. The four classes are martensitic, ferritic, austenitic, and precipitation hardened stainless steels.
