Tungum® vs. 316/316L Stainless Steel, a lesson in history. Please read our latest case study, #Tungum vs. 316/316L Stainless Steel. Why Tungum® alloy tube is chosen instead of 316/316L stainless steel in offshore applications In salt-laden marine atmospheres, #316 stainless steel is susceptible to pitting and crevice corrosion. After several years of salt spray exposure, 316 stainless steel tubing may still look bright from a distance, but closer inspection reveals tell-tale signs of imminent failure to hold pressure. Tungum alloy, however, possesses a natural protection mechanism whereby, on exposure to salt spray, a very thin oxide coating is generated over the exposed surface, no more than two thousandths of an inch thick when complete. The tube becomes discolored, and may even have a verdigris coating, but under the oxide layer the tube material is perfect with the wall thickness unaffected. Operators realized they had a tube material which, when used on appropriate circuits, was capable of lasting the life of the platform without being disturbed.
