316 stainless steel is a molybdenum-bearing austenitic stainless steel, offering enhanced corrosion resistance compared to 304, especially in chloride and acidic environments. Due to its superior pitting and crevice corrosion resistance, excellent mechanical properties, high-temperature strength, and good weldability, it is widely used in marine, chemical, pharmaceutical, and food processing industries. You can find equivalent grades in various international standards, such as X5CrNiMo17-12-2/1.4401 (Europe EN 10088-3), 06Cr17Ni12Mo2/0Cr17Ni12Mo2 (China GB/T 1220), SUS316 (Japan JIS G4303), and 03X17H14M3 (Russia GOST 5632-76).
