What is Stainless Steel?

Stainless Steel, also known as high-alloy steel, is a type of alloy steel that resists rust and other forms of corrosion. High-alloy steels contain a high percentage of alloying elements. As the most common of the high-alloy steels, stainless steel’s alloying element is chromium, which it contains at a quantity of over 10%. Chromium also helps with heat resistance. Stainless steel is used where the properties of steel and resistance to corrosion are both required. It contains sufficient chromium to form a passive film of chromium oxide, also referred to as the latent layer, which prevents further surface corrosion. These factors, combined with its low maintenance, make it an ideal material for many applications. It’s available in coils, sheets, plates, bars, wire, and tubing.
Stainless steel is often used for household appliances in kitchens, laundry rooms, and garages. Some common applications for stainless steel include cookware, cutlery, household hardware, surgical instruments, major appliances, and industrial equipment (for example, in sugar refineries). It’s also regularly found in the automotive and aerospace industries, and in construction materials for large buildings.

 

13-8

13-8 stainless steel alloy (UNS S13800) is a martensitic precipitation-hardening stainless steel that has excellent strength, high hardness, superior toughness, and good corrosion resistance. Compared to other ferrous-base materials alloy 13-8 offers a high level of useful mechanical properties under severe environmental conditions. . Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting.

303

Alloy 303 is a non-magnetic, austenitic stainless steel that is not hardenable by heat treatment. It is the free machining modification of the basic 18% chromium / 8% nickel stainless steel. Alloy 303 was specially designed to exhibit improved machinability while maintaining good mechanical and corrosion resistant properties due to the presence of sulfur in the steel composition; Alloy 303 is the most readily machineable austenitic stainless steel. It is however, fairly resistant to general atmospheric corrosion, general foodstuffs, sterilizing solutions, dyestuffs, most organic chemicals, plus some inorganic chemicals. Like other austenitic grades, Alloy 303 demonstrates excellent toughness, although the sulfur does reduce this a little as well.
Alloy 303 was developed as a free machining grade, and has by far the best machinability of all the 300 series austenitic stainless steels, and indeed has better machinability than most of the 400 series martensitic stainless steels with the exception of the free machining grades. Alloy 303 is not generally recommended for welding due to its high sulfur content which can cause hot cracking. However, if unavoidable, the following procedures may be taken as a guide. Alloy 303 is nonmagnetic in the annealed condition, but can become mildly magnetic following heavy cold working. Annealing is required to rectify if necessary.
Typical applications of alloy 303 are: Architectural Components, Food Processing Equipment, Dairy Equipment, Dying Industry, Hardware and Kitchenware manufacturing and allied industries. Commonly used to manufacture Bolts and Nuts, Bushes, Gears, Shafts, Valve Bodies and Fittings, Aircraft fittings, Gears, Screws, Electrical switchgear components, Bushings, Automatic screw machines and Conveyor systems.

304/304L

Alloy 304/304L is the most widely utilized “18-8” chromium-nickel austenitic stainless steel. It is an economical and versatile corrosion resistant alloy suitable for a wide range of general purpose applications. It is common practice for 304L to be dual certified as 304 and 304L. Alloy 304/304L resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. The alloy has excellent resistance to intergranular corrosion in the as-welded condition. Alloy 304/304L has excellent strength and toughness at cryogenic temperatures. Alloy 304/304L is non-magnetic in the annealed condition. It can be easily welded and processed by standard shop fabrication practices.
Stainless steel Angle Alloy 304/304L has good resistance to atmospheric corrosion, foods and beverages and to many organic and inorganic chemicals in moderately oxidizing to moderately reducing environments. The high chromium content of the alloy provides resistance to oxidizing solutions such as nitric acid up to 55% weight and up to 176°F (80°C).
Alloy 304L Stainless Steel is used in a wide variety of home and commercial applications, including: Food processing equipment, particularly in beer brewing, milk processing, and wine making, Kitchen benches, sinks, troughs, equipment, and appliances, Architectural trim and molding, Automotive and aerospace structural use, Construction material in large buildings, Chemical containers, including for transport, Heat exchangers, Nuts, bolts, screws, and other fasteners in the marine environment, Dyeing industry, Woven or welded screens for mining, quarrying & water filtration.

316/316L

Stainless Steel 316 is an austenitic chromium-nickel stainless steel containing molybdenum. By that type 316 has increased general corrosion resistance, improved resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures.
316 is stronger than 304 at elevated temperatures. Its corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids, acid sulfates and alkaline chlorides.
Type 316L is an extra-low carbon version of Type 316 that minimizes harmful carbide precipitation due to welding. Type 316L is used extensively for weldments where its immunity to carbide precipitation due to welding assures optimum corrosion resistance.
Both 316/316L alloys are non-magnetic in the annealed condition, but can become slightly magnetic as a result of cold working or welding. They can be easily welded and processed by standard shop fabrication practices.
