1. Stainless Steel 316l Coil Corrosion Resistance:

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

2. Stainless Steel 316l Coil Heat Resistance:

• Good oxidation resistance in intermittent service to 1600°F (870°C) and in continuous service to 1700°F (925°C)
• Grade 316L is more resistant to carbide precipitation.

3. Stainless Steel 316l Coil 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.

4. Stainless Steel 316l Coil 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.
