High quality stainless steel coil supplier with guaranteed quality and trustworthy products. Own factory for uncoiling, slitting and surface treatment with competitive price. First-class service.
· 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.
· 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.
· 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.
· 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.
· 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.
· 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.
· 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.
