Due to its resilience in corrosive environments and high strength, 316 stainless steel is frequently used in:
While 316 and 304 are both austenitic stainless steels, 316 offers better resistance to chlorides and acids due to its molybdenum content, making it more suitable for marine and chemical processing environments. For high-stress applications requiring enhanced pitting resistance, 316 is the preferred choice over 304.
