Possible alternative grades to 321 grade stainless steel
Grade
|
Why it might be chosen instead of 321
|
304L
|
The requirement is for resistance to intergranular corrosion, not for high temperature strength
|
3CR12
|
Only mild "high temperature" environment is present… up to about 600°C.
|
304H
|
Only mild "high temperature" environment is present… up to about 800°C.
|
310
|
The temperature of the operating environment is up to about 1100°C - too high for 321 or 321H.
|
S30815
(253MA)
|
The temperature of the operating environment is up to about 1150°C- too high for 321 or 321H.
