Selection of stainless steels for handling nitric acid 304l stainless steel nitric acid Strip surfacing welding
Avoiding localised attack in concentrated acid. To avoid the risk of localised corrosion, especially where post weld heat treatment is impractical, the low carbon, 304L types should be considered. Solution heat treatment (1050 -1100 o C followed by fast cooling) on the standard carbon 304 type can be considered as an alternative. These treatments should also re-dissolve any sigma formed.Selection of Stainless Steel For Handling Nitric Acid HNO3Compostions of 304L type have been used with silicon, phosphorous & sulphur limited to very low residual levels to improve the resistance in hot concentrated nitric acid.
