316 has excellent corrosion resistance to chemicals; the paper and textile industries principally use it. Other common uses for this metal include food processing equipment, chemical processing, nuts and bolts, and medical implants.
Stainless Steel 316L was designed to have a far lower carbon content than its 316 counterpart. As such, 316L is helpful in areas where the avoidance of carbon precipitation is desired. The metal is commonly applied in weldments, where its particular carbon content combined with welding guarantees maximum resistance against general corrosion and also in heavy gauge components. It is estimated that 316L has a better oxidation resistance than type 316, especially in warm marine environments. Once again, the low level of carbon protects it from carbon precipitation. The metal also tends to resist extremely cold temperatures that go down to as low as cryogenic temperatures. Where heat is concerned, 316L exhibits superior creep resistance, heuristic stress to rupture, and greater overall strength than other grades of stainless steel.
Stainless Steel 316Ti is known as the stabilized grade of the 316 types but is also one of only two 316 stainless steels recommended for higher temperature situations. This includes adding a small amount, typically only 0.5% of titanium. The properties of other 316 grades are still very much present. When combined with titanium, it allows 316Ti to be protected from precipitation at higher temperatures, especially where there might be long-term exposure.
316Ti also features an addition of molybdenum in its composition. As with other grades of 316, the molybdenum allows added protection from corrosion and pitting from chloride solutions and increased strength when placed in high-temperature environments. Its high-temperature resistance is yet again compounded by its titanium content that allows 316Ti to be immune to precipitation at these temperatures. It resists acids, especially sulfuric acids, hydrochloric acids, and acid sulfates. 316Ti is used for marine applications like heat exchangers, paper mill equipment, and architectural components.
