316 Stainless Steel, specifically UNS S31600 and UNS S31603, is a non-magnetic chromium-nickel stainless steel that is used in the solution treated or annealed condition. The “L” or “H” designation resembles how much carbon that the metal has in it. Despite the decreased amount of carbon, stainless steel 316L is extremely akin to stainless steel 316 in roughly every aspect. The price for both types is alike, as they share properties such as density, thermal conductivity, magnetism, tensile strength, durability, and corrosion resistance. Stainless steels 316/316L are not hardenable by heat treatment and is one of the most common stainless grades due to its machining capabilities.
Because of its increased chromium %, 316 stainless steel is more resistant to corrosive material. It is also known for its resistance to potable water, but not warm sea water. Heat resistant up to ~1700°F. 316 stainless steels properties and processing make it incredibly resistant to stress-fractures, even at extreme temperatures.
Commonly heat-treated at ~2000°F. Corrosion resistance is obtained if the forgings are given a final anneal. Even though 316 stainless steel can't be hardened through a process of heat-treatment, type 316 is extraordinarily solid and ductile. Grade 316 steel is easily cold treated in forms like bent and deep drawing without deadlock. Because 316 stainless steel is so strong, it is actually more challenging to process than other 300-series stainless steels.
