Strength of C-22 Vs SS-410 & SS-403

Strength of C-22 Vs SS-410 & SS-403

Strength of C-22 Vs SS-410 & SS-403

(OP)
Good Day All
One question?? from mechanical strength point of view which alloy shows more promising strength that is If I compare C-22 with SS-410 and SS-403. I have proposed in using C-22 alloy as MOC for Impellors in Recycle Gas blowers. As C-22 is more chlorine (WET/DRY)Corrosion resistant as compare to SS-410 and 403 but from strength point of view does C-22 exhibits Good strength equally to 410 and 403.
kindly reply at earliest

What service temperature?

RE: Strength of C-22 Vs SS-410 & SS-403

Since this sounds like a welded structure, I would guess that you are not heat treating after fabrication, therefore are using 410S (the low carbon ferritic version).
If that is true then C22 will have at least equal if not superior strength.  And since you won't need a corrosion allowance you can make it thinner, reducing stresses.

The service temp for operating would be around 200-250C in recycle gas blowers. what be the strength of C-22 at this temp??? as comparing with SS-410.
Thanks

For design purposes, I would use the following allowable stress values from ASME B&PV Code, Section II

For C-22 (UNS 06022) @ 500 deg F  26.5 Ksi
For 410 (annealed) @ 500 deg F  17.2 Ksi

403 would be similar to 410 in an annealed condition. The above allowable stress values are for time independent properties, where either yield or tensile stress would set the allowable stress value.
