What does AISI 304 / 304L stand for?

The material "AISI 304 stainless steel / inox" is very well-known under this name in many parts of the world. The abbreviation AISI stands for "American Iron and Steel Institute". The first figure of the AISI 304 designation indicates that the material belongs to the group of austenitic stainless steels. The remaining two figures indicate the ordinal number in its category.

Product Details

304L Stainless Steel Coil Description

304L stainless steel coil is a variant of 304 stainless steel coil with a lower carbon content and is used where welding is involved. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone close to the weld, and the precipitation of carbides may lead to intergranular corrosion of stainless steel in certain settings. Basically, using 304L spares the need to anneal weld joints prior to using the completed metal form, saving time and effort. Generally speaking, both 304 and 304L stainless steel coils can be used for many of the same applications. The differences are often minor enough that one isn’t considered massively more useful over the other. 304L stainless steel coil is widely used in fields such as food processing equipment, building materials, automobile parts.
