NACE TM0177 – Laboratory Testing of Metals for Resistance to Sulfide Stress Cracking and Stress Corrosion Cracking in H2S Environments

Testing of metals subjected to tensile stresses for resistance to cracking failure in low-pH aqueous environments containing H2S. Facilitates testing conformity so that data from different sources may be compared on an equal basis. Covers sulfide stress cracking (room temperature, atmospheric pressure) and stress corrosion cracking (elevated temperatures and pressures). Discusses environment cracking variability, test reagents and solutions, material properties, test vessels and fixtures, and testing at elevated temperature/pressure.

The four test methods described are:
– Method A Tensile Test
– Method B – Bent-Beam Test
– Method C – C-Ring Tes
t- Method D – Double-Cantilever-Beam (DCB) Test.

General guidelines to determine the appropriateness of each test method also are given. Key words: austenitic stainless steels, hydrogen sulfide, metals, sulfide stress cracking.
