Sulfide Stress Cracking Corrosion (SSC)

About Sulfide Stress Cracking Corrosion (SSC)

Mett-Bio Metallurgical Testing & Services with its state of the art equipment setup consisting of Two-point bend, Four point bend, C-Ring setups and experienced personnel conducts SSC testing as per Methods A, B, C and D test for resistance of carbon and low alloy steels and CRAs. These

Tests are performed in our ISO 17025:2005 NABL accredited lab under the standard sour conditions or as per specific field conditions.

 NACE TM0177, Method A - Constant Load (Tensile) Test

 NACE TM0177, Method B - Bent-Beam Test (Two Point , Four Point)

 NACE TM0177, Method C - C-Ring Test

 NACE TM0177, Method D - Double-Cantilever-Beam (DCB) Test

Mett-Bio Metallurgical Testing & Services has in housedeveloped AUTOCLAVE for simulating high Pressure and highTemperature (300C) conditions which prevails in refineries and chemical industries.

Failed test pieces are examined for crack sensitivity ratio, crack length ratio and crack thickness ratio using our optical microscopes.

Typical Outputs:

Time To Failure

Applied Stress Vs Log Of Time To Failure (Under Constant Load Conditions)

Apparent Threshold Stress (Under Circumferential Loading)

Threshold Stress Intensity Factor

Crack Velocity

Crack Growth Rate,

Stress Intensity Factor

Threshold Stress Intensity Factor..
