The higher nickel content in this evaluation permits it to show preferred general consumption safe properties over 304, particularly with respect to setting and hole erosion in chloride situations. Also, Alloy 316/ 316L gives magnificent lifted temperature elastic, crawl and anxiety crack qualities, and remarkable formability and weldability. 316L is the lower carbon form of 316 and is invulnerable from refinement; thusly, it is habitually utilized as a part of substantial gage welded parts.
