Stress corrosion cracking should be considered for all corrosion services where the corrosive liquid may contain chloride. Grade 316, and grade 304, may suffer stress corrosion cracking in solutions containing chloride ions at temperatures over about 60☌. The higher molybdenum content of 316 make it significantly more corrosion resistant than grade 304.ģ16 stainless steel can be used with seawater, provided precautions are taken to avoid crevice corrosion developing under sediments, precipitation and biofouling, and at designed-in crevices.
Pitting and crevice corrosion may occur in waters with higher chloride content, and 2000 ppm is accepted as the upper limit. Grade 316 also has given excellent service in potable water. Best appearance is maintained where the design allows even rain washing of the surface, or where dirt deposits are occasionally washed off the steel. It gives good service in atmospheric conditions, resisting most environments and is often used in marine conditions, or where industrial pollution is heavy. Corrosion Resistanceģ16 stainless steel has excellent corrosion resistance in many environments. Typical Applications for 316 Stainless Steelīrewing and dairy equipment, evaporators, drums, barrels, heat exchangers, chemical and food processing, water treatment plant, chemical processing equipment, architectural and boat fittings exposed to marine and polluted atmospheres are typical uses for grade 316 stainless steel. AvailabilityĪustral Wright Metals can supply this grade as plate, coil, sheet, strip, round, hexagon, flat bar, angles, tube, pipe and welding consumables. The version with guaranteed high carbon, 316H, may be required for elevated temperature service, such as pressure vessels.
#316 stainless steel resistance to chromium chloride full#
The low carbon version, 316L, may be required for full corrosion resistance when sections thicker than about 5 mm are welded. The ease of cleaning and of maintaining a hygienic surface on the steel make it excellent for many purposes. In most applications the steel is used where its corrosion resistance gives long lasting service life and appearance. The very tough and ductile austenitic structure gives grade 316 excellent formability and fabrication characteristics. The 316H version has a guaranteed minimum carbon content, which ensures good strength at high temperatures.ģ16 is a member of the 18/8 chromium nickel family of austenitic stainless steels, with an addition of 2% molybdenum for improved corrosion resistance, particularly to localised corrosion in chloride containing environments. The low carbon version, 316L, may be required for full corrosion resistance when thicker sections are welded. It is an austenitic, corrosion-resistant steel with excellent strength, toughness, fabrication characteristics and weldability. Grade 316 Stainless Steel is the second most commonly used stainless steel, behind 304 stainless steel.
