Product Detail

SS 304L is the low-carbon derivative of Type 304, and although the two types share many of the same properties, it is the differences in carbon content that differentiates them. SS 304L is used for applications where a low carbon count is required, such as in heavy gauge components. Its different composition from Type 304 also eliminates the need for post-weld annealing to effectively maximize corrosion resistance. Additionally, it also possesses a higher work hardening rate.
304L exhibits excellent resistance in a variety of atmospheres and temperatures, along with the corrosion and oxidation that occurs over time. It is often applied in areas of higher temperatures than Type 304 can endure, and its low carbon allow it to be resistant against carbon precipitation. However, like many stainless steels, it is susceptible to warm chlorine environments and can potential pit and crack.
