Applications |
| 1 |
304# |
Better welding Characteristics
with good formability and general corrosion resistance.
Susceptible to intergranular corrosion.
|
General corrosion resistance
in chemical industry requiring welded fabrication; Watch
parts, engine gaskets, flexible hoses, foot rule, door
hinges, capillary tubings and sinks.
|
| 2 |
304L# |
Extra Low – carbon, no
danger of intergranular corrosion during service, welding
or stress-relieving when used below 430oC, Good corrosion
and oxidation resistance.
|
Injectable needles and capillary
tubings. |
| 3 |
316#
|
Best corrosion resistance in
phosphoric, acetic and dilute sulphuric acid, sulphurous
and halogen salt water and against pitting corrosion.
|
Engine gaskets, flexible hoses,
process plant and paper industries equipment. |
| 4 |
316L# |
Extra Low carbon, no danger
of intergranular corrosion when used below 430oC, highly
corrosion resistant, weldable and resistant to sensitisation.
|
Process plant parts particularly
in thick sections. |
| 5 |
317# |
Increased corrosion resistance
than Grade 316.
|
Process plant parts particularly
in thick sections. |
| 6 |
321# |
Stabilized 18:8 , virtually
free from intergranular attack in corrosive media upto
810oC. Weldable and resistant to sensitization. Good corrosion
and oxidation resistance |
Heater elements , process plant,
furnace parts and high temperature tubes. |
| 7 |
