3.3 Sulfide Stress Corrosion Cracking (SSCC)
Resistance
| (1) |
13CR has a high SSCC susceptibility
as shown in below fig; 13CR usage is not advisable
for usage in environments containing a small
amount of H2S ( 0.03atm). |
| (2) |
13CRS has good SSCC resistance in evironments
containing up to 0.03atm H2S. |
| (3) |
Duplex stainless steels (SM22CR, SM25CR, SM25CRW)
are recommendable over marternsitic stainless
steel (SM13CRS) in a small amount of H2S |
