Types 316 and 317 are "18-8" chromium-nickel stainless steels modified by the addition of molybdenum, which greatly increases the corrosion resistance as well as the mechanical properties at elevated temperatures. These grades are non magnetic in the annealed condition and not hardenable by heat treatment. Since they have good cold forming and drawing properties, these grades are outstanding stainless steels suitable for a large number of applications. Manufactured by the electric-furnace process, these grades meet the exacting standards of the aircraft industry. Bars and Plates are available not only in the regular Type 316 analysis, but also in an extra low carbon analysis known as Type 316L. The advantage of the reduced carbon content is that it precludes any harmful precipitation in the 800°-1500°F range, such as might otherwise occur in welding heavier sections. Types 317 and 317L are available in plate and with increased chromium, nickel, and molybdenum contents can be used in even more severe corrosive and high temperature applications.
