316 Stainless Steel

316 stainless steel is an austenitic chromium-nickel alloy enhanced with molybdenum, which significantly improves its resistance to corrosion, particularly against chlorides, industrial chemicals, and marine environments. It offers excellent strength, durability, and formability, making it suitable for demanding applications where exposure to harsh conditions is common. Compared with 304 stainless steel, 316 provides superior resistance to pitting and crevice corrosion, making it widely used in marine engineering, chemical processing, pharmaceutical equipment, food processing, and medical devices. It also maintains good mechanical properties at both high and low temperatures, ensuring reliability across a wide range of operating conditions. It is supplied in flat bar and square bar forms under standards such as ASTM A276/A479. 316 marine-grade stainless steel remains the benchmark for chloride-exposed environments — from offshore hardware to pharmaceutical and food-contact equipment — wherever 304 stainless steel's corrosion resistance isn't sufficient.
