SSC experimental   resistance to hydrogen induced cracking test HIC test         HIC  :  clear;       crack sensitivity ratio CSR  crack length ratio CLR  crack thickness ratio CTR        NACE  TM  standard: 0284-2003  NACE  RM0175-2000      & nbsp;     testing process:       sample size;       according to the standard requirements, test plate thickness of not more than 30mm sample size as shown in Figure 1, the number of samples for each of 3.         with distilled water and analytical pure grade chemical dispensing test solution cost test.         test, defatted samples with soap and water, then rinse with alcohol. The treatment (except oil, grinding) good specimen clamping in organic glass sample holder on the special, into the test container, to solution was injected into the test vessel after sealing the container.         to 2 L / min speed access N21 hours deoxidation. The gas purity of N2 is higher than 99.9%.         close the N2, with a 2.4 liter / minute speed of H2S gas is added for 1 hour, and then H2S ventilation speed reduced to 0.12 L / min, lasting 96 hours.         ventilation is completed, the specimen is removed wash in flowing water, and rinse with alcohol, drying in air cooling.         according to the standard specimen cut and metallographic observation.         100 * for the cross checks according to the requirement of test standard amplification evaluated crack sensitive rate board (CSR), the length of crack sensitive rate (CLR), crack thickness sensitive rate (CTR).         Wuxi Rong Da Chuan Detection Technology Service Co.
