The 316 stainless steel plate is a metal that is a popular product that is used in industries like food, boating/marine, pharmaceutical, textile, paper, dyeing and environmental. Some of the applications this grade of metal is used for include pollution control equipment, chemical processing, tanks, evaporators, boat fittings and heat exchangers. 316 steels are alloyed with molybdenum, chromium and nickel. This makes it harder, stronger and more corrosion resistant. Because of its high resistance, it is able to avoid pitting and crevice corrosion. It also has a great resistance to chemicals, chlorides and warm salt water. This metal is also non-magnetic, which makes it ideal for use in moving parts and instruments.
316 stainless steel plates have great drawing, forming and stamping properties. It is able to be cold worked, forged, machined and welded. When being welded, standard fusion methods can be used. Hot cracking can be avoided by assuring ferrite formation in the weld deposits. The weldability of this metal is poorer than that of 304 and 304L alloys. This is due to the higher content of nickel, which requires that this metal be welded at slower arc welding speeds. It also needs special care to avoid hot cracking, compared to the 304 types.
316 steels have a low content of carbon, which limits the formation of harmful carbides. This is why it’s safe for use in home kitchens and the food and beverage industries. After welding is performed on this steel, post-weld annealing is needed to maintain corrosion resistance. Post annealing is also required after severe cold forming, such as deep drawing, and after forging. Annealing should be done at between 1900 and 2100 degrees F.
