The 316L stainless steel channel is a chromium-nickel metal that is austenitic. This means that it is non-magnetic and is highly resistant to corrosion. This is due to the high content of nickel, chromium and molybdenum. Being alloyed with these elements also makes this stainless steel product more resistant to pitting and crevice corrosion when in chloride environments. It has great tensile strength in elevated temperatures. 316L metals also have excellent weldability and formability. It also has creep and stress-rupture strengths.
The applications this grade of steel is commonly used in include chemical equipment, food prep equipment, laboratory benches, lab equipment, rubber machinery, tanks, heat exchangers, boat fittings, pollution control equipment, evaporators and condensers. Textile, pharmaceutical, food, chemical and paper industries frequently use this alloy for the production of parts.
This metal is able to withstand atmospheric environments better than 304 alloys because it has a higher content of molybdenum and chromium. There is a potential for stress corrosion cracking, crevice corrosion and pitting to occur when in chloride environments that are above 122 degrees F. It is, however resistant in potable water that contains around 1000mg of chloride and has an ambient temperature, reducing to around 500mg at 140 degrees F. Because it is resistant to warm sea water, it is known as a marine grade stainless steel.
316L steel has good oxidation resistance when being serviced in temperatures up to 1600 degrees F and continuously in temperatures up to 1700 degrees F. It is a metal that is highly resistant to carbide precipitation. Annealing can be done to this metal at temperatures between 1900 and 2100 degrees F. Heat treatment cannot be used to harden this metal. It’s recommended that forging not be done at temperatures over 2300 degrees F.
