304/304L is the most widely used Austenitc stainless steel. It accounts for more than 50% of all stainless steel produced, represents between 50%-60% of consumption of stainless materials and fins applications in almost every industry. 304L is a low carbon chemistry of 304, it combined with an addition of nitrogen enables 304L to meet the mechanical properties of 304. 304L often used to avoid possible sensitization corrosion in welded components.lt's non-magnetic in the annealed condition, but can become slightly magnetic as a result of cold working or welding. It can be easily welded and processed by standard fabrication practices.It has excellent resistance to atmospheric corrosion, moderately oxidizing and reducing environments, as well as intergranular corrosion in the as-welded conition It also has excellent strength and toughness at cryogenic temperatures as well.
