What is Hydrogen Induced Cracking - HIC and SOHIC

HYDROGEN INDUCED CRACKING Hydrogen Induced Cracking (HIC) When corrosion of steel occurs in an acid solution (e.g.carbonic acid) containing H 2 S,iron sulphides and hydrogen are formed.The hydrogen is first produced as hydrogen atoms (H) which normally combine rapidly toWet Hydrogen Sulfide (H2S) Cracking InspectioneeringHydrogen Induced Cracking (HIC) is a form of tiny blistering damage caused by a high concentration of hydrogen in steel.The blistering damage tends to form parallelThe hydrogen induced cracking susceptibility evaluation of @misc{etde_506810,title = {The hydrogen induced cracking susceptibility evaluation of USIMINAS API steels under H{sub 2} S and water environment; Avaliacao da susceptibilidade de acos API da USIMINAS a trincas induzidas por hidrogenio em meios contendo H{sub 2} S e agua} author = {Miranda,Fabiano J.F.,Ratnapuli,Rajindra C,and Miyashita,Takashi} abstractNote = {The paper discusses the
