| Typical Applications
 |
Widely used in a variety of applications
requiring superior corrosion resistance or good elevated
temperature strength
|
|
Applications include valve parts, pumps,
tanks, evaporators and agitators, textile processing
equipment and a wide variety of parts exposed to marine
atmospheres
|
|
Type 316 L is used extensively for
weldments where its immunity to carbide precipitation
due to welding assures optimum corrosion resistance
|
Machinability
Type 316 is somewhat more difficult to machine than Type
304 because of its toughness. As large a tool as possible
and great amounts of cutting fluid should be used.
Heavy feeds at slow speeds will machine best.
Weldability
Type 316 and 316L have excellent weldability and are
readily joined by all methods employed with stainless
steel. Weldments of Type 316 may require annealing to
restore maximum corrosion reisistance. Type 316L eliminates
the necessity for annealing except where required for
stress relief. |
Formability
Types 316 and Type 316L can be readily drawn and formed.
Corrosion Resistance
Type 316 provides better corrosion resistance than Type
304. It has excellent resistance to pitting type
corrosion such as encountered in sea coast environment.
It also has good resistance to most chemicalsinvolved
in the paper, textile and photographic industries.
Forgeability
Forging is done by heating to 2200-2300°F and forging.
No forging should be done below 1700°F. Material should
be cooled rapidly after forging and hot forming.
Heat Treatments
ANNEALING: Material is heated to 1950-2050° F, cooled
rapidly in air or water quenched. |
