Type 316 is a molybdenum steel possessing improved
resistance to pitting by solutions containing chlorides
and other halides. In addition, it provides excellent
elevated temperature tensile, creep and stress -
• Type 316 is more resistant to atmospheric
and other mild environments than Type 304. It is
resistant to dilute solutions (i.e. 1-5%) of sulfuric
acid up to 120 deg.F. However, in certain oxidizing
acids, Type 316 is less resistant than Type 304.
• 316 is susceptible to carbide precipitation
when exposed in the temperature range of 800 deg.
- 1500 deg.F. and therefore is susceptible to intergranular
corrosion in the as-welded condition.
• Annealing after welding will restore corrosion
• Type 316L has the same composition as Type
316 except the carbon content is held below 0.03%.
Not unexpectedly, its general corrosion resistance
and other properties closely correspond to those
of Type 316. However, it does provide immunity to
intergranular attack in the as-welded condition
or with short periods of exposure in the temperature
range of 800 deg. - 1500 deg.F. The use of 316L
is recommended when exposure in the carbide precipitation
range is unavoidable and where annealing after welding
is not practical. However, prolonged exposure in
this range may embrittle the material and make it
susceptible to intergranular attack.
• The maximum temperature for scaling resistance
in continuous service is about 1650 deg. F. and
1500 deg.F. for intermittent service.
• May be susceptible to chloride stress corrosion
• Non-hardenable; non-magnetic in the annealed
condition, and slightly magnetic when cold worked.
• Improved corrosion resistance to chlorides.
