Product Description
Introduction
LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
316 (UNS S31600) is a chromium-nickel molybdenum austenitic stainless steel developed to provide improved corrosion resistance to 304/304L in moderately corrosive environments. It is often utilized in process streams containing chlorides or halides. The addition of molybdenum improves general corrosion and chloride pitting resistance. It also provides higher creep, stress-to-rupture and tensile strength at elevated temperatures.
It is common practice for 316L to be dual certified as 316 and 316L. The low carbon chemistry of 316L combined with an addition of nitrogen enables 316L to meet the mechanical properties of 316.
316 resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. It also resists corrosion in polluted marine atmospheres. The alloy has excellent resistance to intergranular corrosion in the as-welded condition. 316/316L has excellent strength and toughness at cryogenic temperatures.
316/316L is non-magnetic in the annealed condition, but can become slightly magnetic as a result of cold working or welding. It can be easily welded and processed by standard shop fabrication practices.
Stainless Steel 316 Applications
▪ Food preparation equipment, especially in chloride environments
▪ Chemical processing, equipment
▪ Laboratory benches and equipment
▪ Rubber, plastics, pulp & paper machinery
▪ Pollution control equipment
▪ Boat fittings, value and pump trim
▪ Heat exchangers
▪ Pharmaceutical and textile industries
▪ Condensers, evaporators and tanks
Related Grades
▪ 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
▪ 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.
