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. In addition, Alloy 316/ 316L provides excellent elevated temperature tensile, creep and stress-rupture strengths, as well as outstanding formability and weldability. 316L is the lower carbon version of 316 and is immune from sensitization; therefore, it is very frequently used in heavy gauge welded components.

STANDARDS:
ASTM/ASME: UNS S31600 / S31603
EURONORM: X1 CrNiMo 17 12 2 / X3 CrNiMo 17 12 2
AFNOR: Z 6 CND 17-11 / Z 2 CND 17-12
DIN: 1.4401 / 1.4404
WELDING CHARACTERISTICS:
Excellent weldability by all standard fusion methods, both with and without filler metals.
Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance, this is not required for grade 316L.
HEAT TREATMENT:
Annealing temperature range is 1900 to 2100°F (1038 to 1149°C).
Cannot be hardened by heat treatment.
Special consideration is needed to compensate for a 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) Best
Corrosion resistance is obtained if the forgings are given a final anneal.
PROCESSING – COLD FORMING:
316/316L types being extremely tough and ductile, can be readily cold worked such as roll form, swaging, cold heading, deep drawing, bent, etc., without difficulty
Severely cold formed parts should be annealed to remove stresses.
MACHINEABILITY:
Type 316/316L is somewhat more difficult to machine than Type 304 because of its toughness.
316/316L machines with chip characteristics that are tough and strong.
Chip breakers and curlers are advised.
As large a tool as possible and great amounts of cutting fluid should be used.
Heavy positive feeds at low speeds should be considered since 316/316L work hardens rapidly.
