GENERAL PROPERTIES

316/316L stainless steel alloy is an austenitic stainless steel grade enriched with molybdenum, enhancing its corrosion resistance significantly over 304, especially in chloride-rich environments. The increased nickel and molybdenum content offer superior pitting and crevice corrosion resistance. Additionally, 316/316L seamless pipes boast excellent tensile strength, creep resistance, and stress rupture strength at high temperatures, coupled with outstanding formability and weldability. The low carbon variant, 316L, avoids sensitization, making it ideal for large welded components.

Specifications: UNS S31600/S31603

APPLICATIONS:

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

CORROSION RESISTANCE:

• 316 Stainless Steel, with its enhanced chromium and molybdenum content, offers superior resistance compared to 304 in various atmospheric environments and numerous corrosive media.
  and molybdenum content.
• However, it is susceptible to pitting and crevice corrosion in warm chloride environments and can experience stress corrosion cracking above approximately 122°F (50°C).
• This grade is deemed resistant to potable water containing up to around 1000mg/L chlorides at ambient temperatures, decreasing to about 500mg/L at
  140°F (60°C).
• Commonly referred to as the "marine grade stainless steel," 316 is not resistant to warm seawater.

HEAT RESISTANCE:

• It boasts excellent oxidation resistance during intermittent service up to 1600°F (870°C) and continuous service up to 1700°F (925°C).
• Grade 316L is more adept at resisting carbide precipitation.

WELDING CHARACTERISTICS:

• 316 Stainless Steel exhibits outstanding weldability using all standard fusion methods, both with and without filler metals.
• For heavy welded sections in Grade 316, post-weld annealing is recommended to ensure maximum corrosion resistance, although it's not necessary for Grade 316L.

HEAT TREATMENT:

• Annealing temperature range is from 1900 to 2100°F (1038 to 1149°C).
• This grade cannot be hardened by heat treatment.
• Special measures should be taken to account for a higher coefficient of thermal expansion to prevent warping and distortion.

PROCESSING - HOT FORMING:

• Most manufacturers suggest a maximum forging temperature between 2100°F and 2300°F.
• Avoid forging below 1700°F (927°C).
• Optimal corrosion resistance is achieved if the forgings undergo a final anneal.

PROCESSING - COLD FORMING:

• Types 316/316L, known for their exceptional toughness and ductility, can be easily cold worked, including roll forming, swaging, cold heading, deep drawing,
  bending, etc., without significant difficulty.
• Severely cold-formed parts should be annealed to alleviate stresses.

MACHINABILITY:

• While Type 316/316L is somewhat more challenging to machine than Type 304 due to its toughness,
• it machines with chip characteristics that are both tough and strong.
• Chip breakers and curlers are recommended.
• Utilize the largest possible tools and substantial amounts of cutting fluid.
• Heavy positive feeds at low speeds are advisable since 316/316L work hardens rapidly.
