CORROSION RESISTANCE:

316L Stainless Steel Rod

• With enhanced chromium and molybdenum content, 316L stainless steel rods offer superior corrosion resistance, surpassing 304 in diverse atmospheric and corrosive environments.
  and molybdenum content.
• However, exposure to warm chloride environments may lead to pitting, crevice corrosion, and stress corrosion cracking above 122°F (50°C).
• This grade is considered resistant to potable water containing up to 1000mg/L chlorides at ambient temperatures, which reduces to about 500mg/L at
  140°F (60°C).
• Although often referred to as the 'marine grade stainless steel,' it is not resistant to warm sea water conditions.

HEAT RESISTANCE:

• Exhibiting excellent oxidation resistance, 316L stainless steel performs well up to 1600°F (870°C) in intermittent service and 1700°F (925°C) in continuous service.
• Grade 316L offers superior resistance to carbide precipitation.

WELDING CHARACTERISTICS:

• With exceptional weldability by all standard fusion methods, 316L stainless steel can be welded both with and without filler metals.
• For Grade 316, heavy welded sections require post-weld annealing to achieve optimal corrosion resistance, a step unnecessary for 316L.

HEAT TREATMENT:

• The recommended annealing temperature range is between 1900°F and 2100°F (1038°C to 1149°C).
• 316L stainless steel cannot be hardened through heat treatment.
• It is essential to account for its higher thermal expansion coefficient to prevent warping and distortion.

PROCESSING - HOT FORMING:

• Most producers suggest a maximum forging temperature between 2100°F and 2300°F
• Forging should not commence below 1700°F (927°C). The best corrosion resistance is achieved with a final anneal.
• Corrosion resistance is obtained if the forgings are given a final anneal.

PROCESSING - COLD FORMING:

• 316/316L stainless steel rods, known for their toughness and ductility, are readily cold worked through methods like roll forming, swaging, cold heading, and deep drawing.
  bent, etc., without difficulty
• Severely cold-formed parts should undergo annealing to relieve stresses.

MACHINEABILITY:

• Due to its toughness, Type 316/316L stainless steel rods are more challenging to machine compared to Type 304.
• 316/316L produces chips that are tough and robust.
• Using chip breakers and curlers is recommended.
• Opt for large tools and ample cutting fluids.
• Consider heavy positive feeds at low speeds since 316/316L work hardens rapidly.
