316L

  Grade 316L (UNS S31603, EN 1.4404) is molybdenum-bearing austenitic stainless steels, which is more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Grade 304. The low carbon chemistry of 316L combined with an addition of nitrogen enables 316L to meet the mechanical properties of 316.

Grade 316L is often utilized in process streams containing chlorides or halides. The addition of molybdenum improves general corrosion and chloride pitting resistance. It also offers higher creep, stress-to-rupture, and tensile strength at elevated temperatures. In addition to excellent corrosion resistance and strength properties, the Grade 316L Cr-Ni-Mo alloys also provide excellent fabricability and formability which are typical of the austenitic stainless steels.


PROPERTIES

  Grade 316L may be considered for a wide variety of applications where one or more of the following properties are important:

  • Resists atmospheric corrosion, more resistant than Grade 304
  • Resists corrosion in polluted marine atmospheres
  • Heat Resistance
  • Heat Treatment
  • Prevention of product contamination
  • Resistance to oxidation
  • Easily welded and processed by standard shop fabrication practices.
  • Excellent formability
  • Hot and cold working
  • Beauty of appearance
  • Ease of cleaning
  • Good strength and toughness at cryogenic temperatures
  • Ready availability of a wide range of product forms

RAW MATERIAL FINISHS
No.1

A rough, dull surface, which results from hot rolling to the specified thickness, followed by annealing and descaling.

Range 914 (3') 1000 1219 (4') 1250 1500 1524 (5')
3.0mm~10.0mm
12.0mm~100.0mm        
2D

A dull finish which results from cold rolling followed by annealing and descaling, and may perhaps gets a final light roll pass through unpolished rolls. A 2D finish is used where appearance is not a concern.

Range 914 (3') 1000 1219 (4') 1250 1500 1524 (5')
0.3mm ~ 3.0mm
30GA ~ 11GA
0.012" ~ 0.1196"
2B
(Mill Finish)

A bright, cold-rolled finish resulting in the same manner as 2D finish, except that the annealed and descaled sheet received a final light roll pass through polished rolls. This is the general-purpose cold-rolled finish that can be used as is, or a preliminary step to polishing.

Range 914 (3') 1000 1219 (4') 1250 1500 1524 (5')
0.3mm ~ 3.0mm
30GA ~ 11G A
0.012" ~ 0.1196"
BA
(Bright Anneal)

The bright annealed mill surface is obtained by annealing the material under an atmosphere, so that scale is not produced on the surface.

Range 914 (3') 1000 1219 (4') 1250 1500 1524 (5')
0.3mm ~ 2.0mm    
30GA ~ 14GA
