The presence of molybdenum gves this stainless steel better overall corrosion resistance properties than types 301 and 304 stainless steel. Type 316 gives useful service at room temperature in sulphuric acid of concentrations lower than 15% wt. and greater than 85% wt. It also resist chloride attack and is often used in marine environments.
Alloy selection for service in sulphuric acidTypes 316 and 316L, are generally resistant to strong sulphuric acid at ambient temperature and, unlike carbon steel and cast iron, resist erosion-corrosion. Corrosion resistance of these grades is good up to about 6 m/s (20 ft/s) in the absence of abrasive particles (although normal design would be limited to about 2-3 m/s [6.5-10 ft/s]).

Corrosion resistance levels in stainless steel - Ryerson
MartensiticFerriticAusteniticIn general, martensitic stainless steels are considered moderate when it comes to corrosion resistance. Like low alloy or carbon steels, martensitic stainless steels are similar in structure to ferritic, but can be hardened or strengthened by heat treatmentwhich can also make them more brittle. This is due to the addition of carbon. The main alloying element of this family is chromium. The oil industry is a heavy user of martensitic stainless steel, as is the medical fieldprimarily for surgical equipment. Among the most Corrosion-Resistant 316 Stainless Steel Corrosion-Resistant 316 Stainless Steel. 2 Severe Environment Dampers Greenheck was the first manufacturer to have a complete line of dampers made from all 316 stainless steel material as a standard product offering. We have over 20 models, including dynamic fire dampers, smoke
resistant in this acid. When we immerse coupons in 70% MSA, sometimes corrosion starts immediately and sometimes the alloy is passive from the beginning. Immersion tests as well as electrochemical experiments were conducted on Aisi 316L stainless steel (1.4404 according to EN 10028-7). The results show the random behavior
Effects of nitric acid passivation on the pitting Dec 01, 2000 · Samples of 316 stainless steel have been subjected to passivation treatments at ambient temperature for 1 h in solutions of up to 50 wt% nitric acid.
Nitric Acid Resistant Materials - Waverley BrownallMar 18, 2017 · Nitric Acid:Stainless Steel Exception. For nitric acid, stainless steel 304 is often used in a replacement for 316, which is the opposite solution for most corrosion resistant tactics (for nitric.) The British Stainless Steel Association recommends for over
Type 316 is more resistant to corrosion that Type 304, especially chloride's pitting attack, and it is widely used in chemical processing because of its increased resistance to aggressive agents. In rural atmospheres, virtually all stainless steels will give completely satisfactory service in terms of atmospheric corrosion resistance.
Understanding Stainless Steels Corrosion-Resistant
How Does Stainless Steel Resist Corrosion?Stainless Steel and Chemical Compounds:What to ConsiderSpecialized Types of Stainless Steel Corrosion and DamageFinal ThoughtsWhile various stainless steel grades might differ in their metallurgic composition and alloying or manufacturing processes, one trait they all share is a passivation layer. This layer of chromium oxide forms when the surface of the metal is exposed to oxygen. The layer is too thin to observe directly and under most circumstances remains clear. This allows the finished texture of a stainless steel product to show through and provides a variety of appearance options from high gloss to matte.
