What is 304 stainless steel grade

304 grade is the most common form of stainless steel used around the world. It contains between 16 and 24 percent chromium and up to 35 percent nickel—as well as small amounts of carbon and manganese. It is also known as the 18-8 because it contains 18 percent chromium and 8 percent nickel. 304 stainless steel has a high resistance to rust. It withstands corrosion from most oxidizing acids and is often used for kitchen and food applications. However, it is susceptible to corrosion from chloride solutions. Chloride ions can create localized areas of corrosion, called “pitting,” which can spread beneath protective chromium barriers to compromise internal structures. Solutions with as little as 25 ppm of sodium chloride can begin to have a corrosive effect.

Stainless steel 304 grade has excellent corrosion resistance in a wide range of atmospheric environments and many corrosive media. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60°C.

304 stainless steel grade is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. SS 304 grade also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

Uses of 304 stainless steel grade

304 ss grade is especially suited for all types of dairy equipment – milking machines, containers, homogenizers, sterilizers, and storage and hauling tanks, including piping, valves, milk trucks and railroad cars. This 18-8 alloy is equally serviceable in the brewing industry where it is used in pipelines, yeast pans, fermentation vats, storage and railway cars, etc. The citrus and fruit juice industry also uses 304 ss grade for all their handling, crushing, preparation, storage and hauling equipment.

304 ss grade is also used for the dye tanks, pipelines buckets, dippers, etc. that come in contact with the lormic, acetic, and other organic acids used in the dyeing industry.
