CORROSION RESISTANCE:

316L Stainless steel rod

• Recognized for its superior resistance, 316L stainless steel rod stands out due to its increased chromium and molybdenum content, making it significantly more resilient than 304 in various atmospheric and corrosive environments.
  and molybdenum content.
• While 316L is robust, it remains susceptible to pitting and crevice corrosion in warm chloride environments and stress corrosion cracking above 122°F (50°C).
• 316L stainless steel is generally considered resistant to potable water with chloride levels up to 1000mg/L at ambient temperatures, diminishing to about 500mg/L at 140°F (60°C).
  140°F (60°C).
• Often referred to as 'marine-grade stainless steel,' 316L is, however, not resistant to warm seawater.

HEAT RESISTANCE:

• 316L demonstrates excellent oxidation resistance, enduring intermittent service up to 1600°F (870°C) and continuous service up to 1700°F (925°C).
• Grade 316L is particularly resistant to carbide precipitation, enhancing its durability.

WELDING CHARACTERISTICS:

• 316L offers outstanding weldability through all standard fusion methods, whether or not filler metals are used.
• For maximum corrosion resistance in heavy welded sections of Grade 316, post-weld annealing is necessary, a step not required for 316L.

HEAT TREATMENT:

• The annealing temperature range for 316L stainless steel is between 1900 to 2100°F (1038 to 1149°C).
• It cannot be hardened by heat treatment.
• Special consideration must be given to compensate for a higher coefficient of thermal expansion to prevent warping and distortion.

PROCESSING - HOT FORMING:

• Most producers recommend maintaining a maximum forging temperature between 2100°F and 2300°F.
• Avoid forging below 1700°F (927°C) for optimal results.
• To achieve the best corrosion resistance, ensure forgings receive a final anneal.

PROCESSING - COLD FORMING:

• 316/316L stainless steel rods are extremely tough and ductile, making them highly amenable to cold working processes such as roll forming, swaging, cold heading, deep drawing, and bending without significant difficulty.
  bent, etc., without difficulty
• Parts that are severely cold-formed should undergo annealing to alleviate stresses.

MACHINEABILITY:

• Machining Type 316/316L stainless steel rods is somewhat more challenging than Type 304 due to their toughness.
• 316/316L rods produce tough and strong chips during machining.
• Utilizing chip breakers and curlers is highly recommended.
• Employing large tools and abundant cutting fluid is essential.
• Heavy positive feeds at low speeds should be considered to counteract rapid work hardening of 316/316L.
