Stainless Steel 316L

316/316L stainless steel has a high resistance to many chemical corrodents and marine atmospheres. United Performance Metals offers both 316/316L stainless steel sheet and coil. 316/316L stainless steels are more resistant to general corrosion and pitting/crevices than conventional austenitic stainless steels. 316/316L stainless steels also offer higher creep, stress-to-rupture and tensile strength at elevated temperatures. 316/316L are also well suited for fabricated or formed applications.

Types 316 (UNS S31600) & 316L (S31603), are molybdenum-bearing austenitic stainless steels which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304. These alloys also offer higher creep, stress-to-rupture and tensile strength at elevated temperature.

Common Applications of 316/316L Stainless Steel:

  • Oil & petroleum refining equipment
  • Food processing equipment
  • Pulp and paper processing equipment
  • Soap and photographic handling equipment
  • Textile Industry Equipment
  • Architectural
  • Pharmaceutical processing equipment

Types 316, and 316L are available in sheet, strip and plate to ASTM A240 and ASME SA-240 and other pertinent specifications.

Duplex 2205® Stainless Steel Bars

UNS S31803/UNS S32205

UNS S31803 and UNS S32205 are commonly referred to as Duplex 2205® material, whose “Duplex” name is derived from the mixed microstructure which contains about equal portions of ferrite and austenite. Developed more than 70 years ago in Sweden precisely for the sulfite paper industry where the duplexes were used to combat corrosion problems caused by chloride-bearing cooling waters and other aggressive chemical products. Since then there have been advancements in the composition such as the deliberate addition of nitrogen as an alloying agent, which afterward quickly made Duplex the “workhorse” of stainless steels.

 

Benefits of Duplex include:

good weldability and workability, high resistance to corrosion fatigue, stress corrosion cracking (especially chloride stress corrosion cracking), erosion, and high energy absorption. Other advantages of Duplex are higher heat conductivity and low thermal expansion compared to austenitic stainless steels, high strength, good resistance to sulfide stress corrosion, and high resistance to pitting and crevice to corrosion. Duplex 2205® accounts for over 80% of the total usage of Duplex stainless steels throughout the world because of its superior workability as well as corrosion resistance.


Industries that use Duplex include:

  • Chemical
  • Desalination
  • Material handling
  • Oil and Gas extraction
  • Pulp and Paper
  • Petrochemical
