Type 302 is the basic "18-8" chromium-nickel stainless steel. It combines excellent mechanical properties with remarkable resistance to many corrosive agents encountered in domestic and industrial use. It is non-magnetic in the annealed condition and not hardenable by heat treatment. Both hardness and tensile strength can be increased by cold working. This is an electric-furnace product manufactured to meet the exacting standards of the aircraft industry.

The analysis of Type 304 is similar to that of Type 302, except that Type 304 is modified by lowered carbon content This provides good resistance to corrosion in welded construction where subsequent heat treatment is not practicable. Bars and Plates are available not only in the regular Type 302 and 304 analyses, but also in an extra low carbon analysis, known as Type 304L. The advantage of this analysis is that it precludes any harmful precipitation in the 800°-1500°F range, such as might otherwise occur in welding heavier sections.

Type 303 is "18-8" chromium-nickel stainless steel modified by the addition of selenium or sulphur, as well as phosphorus, to improve machinability and non- seizing properties. It is the most readily machinable of all the chromium-nickel arades and has good corrosion resistance It is non-magnetic in the annealed condition and not hardenable by heat treatment. Tensile strength and hardness can be increased by cold working. It is manufactured by the electric-furnace process and meets the exacting requirements of the aircraft industry.

Type 310S is an austenitic chromium-nickel stainless steel that has excellent oxidation resistance at higher temperatures. This alloy resists oxidation or scaling up to 2000°F Strength at elevated temperatures is similar to the other 18-8 types so stresses at elevated temperatures should be kept low. Corrosion resistance at room temperature is better than Type 304 due to its higher chromium and nickel content. This alloy is non-magnetic in the annealed condition and non-hardenable by heat treatment.

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.

Type 410 is the basic chromium grade of stainless steel. It combines good corrosion resistance with the ability to develop hardness and mechanical properties by conventional heat treating methods that are similar to those of 4130 alloy steel. It is magnetic in all conditions.

Type 416 is a chromium grade of stainless steel modified by the addition of phosphorus and sulphur to produce a free-machining steel. It is the most readily machinable of all stainless steels A wide range of mechanical properties may be obtained by conventional heat treating methods. It is magnetic in all conditions.

This is a high carbon chromium stainless steel, capable of developing high hardness and mechanical properties by conventional heat treating methods. It exhibits best corrosion resistance in the hardened condition. It has excellent resistance to wear and abrasion and is magnetic in all conditions. It develops the highest hardness of the stainless steels.

This is a chromium-nickel grade of stainless steel that may be hardened by a single low-temperature precipitation-hardening heat treatment. Excellent mechanical properties at a high strength level may be obtained by such treatment. Scaling and distortion are minimized. This material should not be used in the solution treated condition.
The strength and corrosion resistance properties of 17-4 hold up well in service temperatures up to 800°F.
Fabrication techniques for this steel are similar to those established for the regular stainless steel grades. This material machines well, has excellent welding characteristics, and forges easily. The combination of excellent mechanical and processing properties makes this grade adaptable to a wide variety of applications.
