Quiz on Sulphide Stress Corrosion Welcome to your Quiz on Sulphide Stress Corrosion 1. Sulphide Stress corrosion occurs Because of Tensile Stress Presence of water Presence of Hydrogen Sulphides Combined effect of all of the above 2. Sulphide Stress Cracking (SSC) is one of the forms of Hydrogen Embrittlement True False 3. Sulphide Stress Cracking (SSC) occurs in high strength steels and in localized hard zones True False 4. Sulphide Stress Cracking (SSC) occurs in Iron alloys because of restricted slip Capabilities True False 5. Sulphide Stress Cracking (SSC) occurs when the hardness of steel is greater than 22 on Rockwell C scale is less than 22 on Rockwell C scale 6. Sulphide Stress Cracking (SSC) is facilitated when Boddy centered cubic structure is there High strength steels are there H2S environment is present All of the above 7. Sulphide Stress Cracking (SSC) is generally found around the welds True False 8. In Sulphide Stress Cracking (SSC), crack will propagate in direction perpendicular to the tensile stress True False 9. In Sulphide Stress Cracking (SSC) Atomic hydrogen diffuses into the steel & causes embrittlement in the heat-affected zones True False 10. Sulphide Stress Cracking (SSC) can be prevented by Controlling the stress level Applying Post Weld Heat Treatment Avoid exposure of Hydrogen Source All of the above 1 out of 5
