304 Stainless Steel Sheet, Coil, and Plate - AMS 5511, 5513
304 stainless steel (AMS 5513), often referred to as 302, is the most common austenitic stainless steel grade. 304 SS contains a higher chromium and lower carbon content than other variations of type 302. It can be used in an "as welded" condition, while 302 must be annealed. AISI 304 is used in a variety of household and industrial applications, especially fasteners and food processing equipment.
Type 304 materials can be used in the welded condition as opposed to the annealed condition and still maintain resistance to corrosion and lend themselves to many types of fabrication. These grades resist corrosion and are often used in the food industry.

The most common austenitic grade is type 304. All other grades are developed from the 18-8 base by adding alloying elements to provide special corrosion-resistance, improved properties or better weldability. Type 304 SS makes up over 60% of all the stainless steel made in the world today.
The wide usage of 304 stainless in food, beverage and pharmaceutical applications reflects the corrosion resistance qualities of these materials. These industries demand that materials do not release significant quantities of contaminants into the product. They must also be easily cleaned. For example, liquid blending and 304 steel storage tanks are readily cleaned, providing proper hygiene in food prep as well as food and beverage handling. Commercial dishwashing detergents eliminate 97% of microorganisms adhering to stainless steel surfaces. Flavor and color are kept intact, with no impact from contact with the tank material.
Another innovative use of 304 materials can be found in architectural planning. Sustainable engineering provides for a building's longevity and safety. Design guidance for stainless steel structures incorporates the ability to hold up against the most severe natural disasters and even considers the resilience to withstand what we consider normal weather impact over time. One example of sustainable engineering can be found in the National Archives of Canada in Gatineau, Quebec. This impressive structure was designed to withstand flooding and seismic events. The characteristics of nickel-containing grade 304 steel used in the structure provide safe-keeping for the country's most precious historical documents.
