316/316L stainless steel alloy is a superior austenitic stainless steel pipe enriched with molybdenum. The added nickel and molybdenum content significantly enhance its corrosion resistance compared to 304, particularly in chloride conditions prone to pitting and crevice corrosion. Additionally, 316/316L seamless pipes boast exceptional high-temperature tensile strength, creep, and stress rupture strength, outstanding formability, and weldability. The low-carbon variant, 316L, prevents sensitization, making it ideal for large-size welded components.
Specifications: UNS S31600/S31603.
