304/304L Stainless Round Bar Stock

304 and 304L Stainless are the most widely used austenitic stainless steels.

304/304L Stainless

304 Stainless is the most widely used austenitic stainless steel due to its composition.

It contains 18 percent chromium and 8 percent nickel. That is why it is also the most expensive. Not only that, it is referred to as “18/8” stainless steel. Meanwhile, 304L has a decreased carbon concentration. It has slightly lower mechanical properties than ordinary stainless steel 304. However, because of its adaptability, it continues to be widely used today.

Machinability & Welding

304 Stainless possesses excellent forming and welding characteristics. It also has excellent corrosion resistance and strength. On the other hand, with 304 decreased carbon concentration, deleterious carbides are less likely to be formed. As a result, it can be welded in high-corrosion environments, eliminating the need for annealing in these environments.


It is undoubtedly a big help in many industries because of its incredible characteristics. Kitchen appliance parts, sinks, utensils, pots, and stoves are some of the many 304/304L Stainless applications.
