About 304 Stainless Steel

The most commonly used of the austenitic stainless steel, the 304 grade is made up of 8-10.5 percent of nickel and 18-20 percent of chromium. Alloys also include other elements – including carbon, manganese and silicon – with the rest of the composition being primarily iron. With the high nickel and chromium content, the 304 grade of stainless steel offers excellent protection against corrosion.

The most widely used types of stainless steel are graded as 304 and 316. The grading system used to classify these two steel grades comes from a numbering system started by the American Iron and Steel Institute (AISI), one of the oldest trade unions that dates back to 1855. These classifications indicate their compositions, with most stainless steels rated in the 200s and 300s considered austenitic. The austenitization process involves heating the iron, iron alloy, or steel to a point where it changes its crystalline structure from ferrite to austenite. Though difficult to distinguish between the two with the naked eye, the distinctive properties between 304 vs 316 stainless steel make each better for certain applications.
