316 stainless steel has good oxidation resistance in intermittent use below 1600 o C and in continuous use below 1700 o C.It is best not to act continuously with 316 stainless steel in the temperature range of 800-1575 o C,but the stainless steel has good heat resistance when used continuously outside this temperature range.316 Stainless Steel Rust/Pitting - FinishingIt is the most corrosion resistant alloy for seawater and your swimming pool is probably not any more corrosive than the sea.UNS S031600 is an okay stainless but where it is in applications where corrosion is absolutely forbidden such as surgical pins used to repair broken bones in the body,a modification of 316 known as 316L is used.
The difference between 316 and 316L stainless steel is that 316L has a .03 max carbon and is good for welding whereas 316 has a mid range level of carbon.316 and 316L are austenitic alloys,meaning that these stainless steel products gain corrosion resistance from use of a nonmagnetic solid solution of ferric carbide or carbon in iron in the 316/316L Stainless Steel - Penn StainlessGeneral Properties.Alloy 316/316L is molybdenum-bearing austenitic stainless steel.The higher nickel and molybdenum content in this grade allows it to demonstrate better overall corrosion resistant properties than 304,especially with regard to pitting and crevice corrosion in chloride environments.
