CORROSION RESISTANCE:

316L Stainless Steel Rod

• Generally more resistant than 304 in a variety of atmospheric environments and many corrosive media, thanks to the increased chromium
  and molybdenum content.
• Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above 122°F (50°C).
• Considered resistant to potable water with up to 1000mg/L chlorides at ambient temperatures, reducing to about 500mg/L at
  140°F (60°C).
• Often regarded as 'marine grade stainless steel,' but it is not resistant to warm seawater.

HEAT RESISTANCE:

• Exhibits good oxidation resistance in intermittent service up to 1600°F (870°C) and in continuous service up to 1700°F (925°C).
• Grade 316L shows greater resistance to carbide precipitation.

WELDING CHARACTERISTICS:

• Boasts excellent weldability by all standard fusion methods, with or without filler metals.
• Heavy welded sections in Grade 316 require post-weld annealing to maximize corrosion resistance, unlike grade 316L.

HEAT TREATMENT:

• The annealing temperature range is between 1900 and 2100°F (1038 to 1149°C).
• Cannot be hardened by heat treatment.
• Special considerations are required to compensate for the higher coefficient of thermal expansion to avoid warping and distortion.

PROCESSING - HOT FORMING:

• Most producers recommend a maximum forging temperature between 2100°F and 2300°F.
• Do not forge below 1700°F (927°C). Maximum corrosion resistance is achieved if the forgings receive a final anneal.
• Corrosion resistance is optimized if the forgings are given a final anneal.

PROCESSING - COLD FORMING:

• 316/316L stainless steel rods are extremely tough and ductile, making them readily cold-workable through processes such as roll forming, swaging, cold heading, deep drawing,
  bending, and more, without difficulty.
• Severely cold-formed parts should be annealed to relieve stress.

MACHINEABILITY:

• Type 316/316L stainless steel rods are somewhat more challenging to machine than Type 304 due to their toughness.
• 316/316L machines with chip characteristics that are tough and strong.
• Using chip breakers and curlers is advised.
• Utilize the largest tools possible and ample cutting fluid.
• Consider using heavy positive feeds at low speeds, since 316/316L work hardens rapidly.
