316 L It is a fashionable austenitic stainless steel, and is disgusting in various applications. 「L」 It represents low carbon and has high weldability and reduces the risk of carbide precipitation. By adding 2 to 3% of molybdenum, corrosion resistance can be improved, and especially in the environment rich in chlorides such as marine and chemical industry, it can be resistant to pitting corrosion and crevice corrosion. Bad conditions show better performance than 304.
