Characteristics
SUS316 is an austenitic stainless steel containing molybdenum, making it the second most widely used stainless steel after SUS304. It offers better corrosion resistance than SUS304, especially in chloride-containing environments, and shows excellent resistance to pitting and crevice corrosion.
