Hydrogen sulfide (H2S) corrosion test is mainly based on the standard of NACE, TM-0284 NACE-0177 and GD/T8650. Test solution is divided into A, B, C three kinds of solution. A solution in a certain amount of distilled water or deionized water with dissolved 5.0wt% sodium chloride (NaCl) acetic acid and 0.5wt% (CH3COOH), B solution by dissolving sodium acetate in distilled water or deionized water 5.0wt%, sodium chloride, 2.5wt% acetic acid and 0.41wt%, C by sodium acetate solution dissolved in distilled water deionized water or 0.4g/L (5Mm and CH3COONa) and the service conditions of the same concentration of chloride (sodium chloride). The test solution C tends to be used for martensitic stainless steel.
TM0177-2005 GB/T; 4157-2006 SSC:NACE.
TM0284-2011 GB/T; 8650-2006 HIC:NACE.
Hydrogen sulfide corrosion test is an evaluation of the corrosion resistance of materials in wet hydrogen sulfide environment. The cracking forms include: sulfide stress cracking (SSC) / stress corrosion cracking (SCC), hydrogen stress cracking, hydrogen induced cracking (HSC) (HIC), (SWC), soft ladder crack zone cracking (SZC), stress oriented hydrogen induced cracking (SOHIC).
SSC hydrogen sulfide stress corrosion cracking test, there are five main methods:
A - SSC method - standard tensile test;
B - SSC method - standard bending test;
C - C method - standard SSC - ring test;
D - SSC method - standard double cantilever beam test;
SSC - four point bending method
