Umbhobho we-Hydrogen sulfide corrosion resistant corrosion iron esetyenziswa ikakhulu ukwenza nokuthutha umbhobho werhasi emuncu.Ngokuphuculwa koxinzelelo lonikezelo kunye nokunciphisa igesi kwimbono yeendleko ze-desulfurization, ngamanye amaxesha ngaphandle kwe-desulfurization yeemeko zemibhobho yegesi, ukwenzela ukuba imibhobho enjalo isebenzise ukuxhathisa umbhobho kwi-hydrogen sulfide.
I-Hydrogen sulfide corrosion resistant steel forumbhobho weoyilekunye nombhobho wegesi yeyona nto inzima kakhulu ukuvelisa uhlobo lwentsimbi, ngenxa yokucoceka kwayo kwentsimbi etyhidiweyo, ulawulo lokwahlula i-billet kunye neemfuneko ezilawulwayo zokuqengqeleka kunye nokupholisa kweenkqubo eziphezulu zesinyithi zemveli azikwazi ukuhlangabezana neemfuno.

Ngokuqhelekileyo kwindawo yegesi ye-asidi, izizathu zokungaphumeleli kwemibhobho zimbini: enye yi-sulfide yoxinzelelo lwe-corrosion cracking, ebhekiswe kwi-SSC.Isiphene sikwindawo ephezulu yamandla entsimbi kunye noxinzelelo lwangaphakathi kunye ne-hydrogen sulfide corrosion phantsi kwesenzo se-medium kunye nolwalathiso loxinzelelo lwe-perpendicular cracks.Kwimibhobho kwinkqubo yenkonzo, umbhobho wensimbi ophezulu ohambelana ne-SSC.

Enye kukuqhekeka okubangelwa yi-hydrogen, okubhekiswa kwi-HIC.Iintanda ngenxa yoxinzelelo oluphezulu lwegesi ye-hydrogen sulfide kwi-corrosion yensimbi ngaphakathi kwe-hydrogen eveliswa kwindawo edibeneyo kunye nokwahlula okubangelwa ukutyetyiswa komphezulu ohambelana nodonga lokuqhekeka.I-HIC yenzeka ikakhulu kwintsimbi esezantsi, ephakathi-yomelele etyaliweyo.
