I-Hydrogen I-Sydrosion inokuthi yenzeke kwi-Amomonia Syntheris, i-hydrogen i-hydrocyling upeptions ye-hyddroegen kunye ne-Petroleum ye-Petroleum. I-Carbon Steel ayifanelekanga ukuba isetyenziswe kwi-hydrogen ephezulu yoxinzelelo lwe-hydrogen ngaphezulu kwe-232 ° C. I-hydrogen inokuxakaza kwintsimbi kwaye iphendule nge-iron carbide kwimida yengqolowa okanye kwimimandla ye-pearlic ukuvelisa i-methane. I-Methane (igesi) ayinakuphazamisa ngaphandle kwentsimbi kwaye iqokelele, ivelise amabala amhlophe kunye neendawo ezinqabileyo okanye ezinye zezi zentsimbi.
In order to prevent the production of methane, carburization must be replaced by stable carbides, steel must be added to chromium, vanadium, titanium or drill. Kubhalwe ukuba i-chromim ivumela amaqondo obushushu aphezulu enkonzo kunye noxinzelelo lwe-hydrogen kwi-Foll kwi-chromium carbide kwezi ntaka, kwaye azinzile kwi-hydrogen. I-Chromium Steels kunye ne-Austitotic Staiels ze-rosional eziqulathe ngaphezulu kwe-12% ye-chromiyam iyosulela kuzo zonke izicelo ezaziwayo phantsi kweemeko ezinzima zenkonzo (amaqondo obushushu ngaphezulu kwe-593 ° C).
Uninzi lweentsimbiKwaye izabelo azisabi kwi-molecular nitrogen kwiqondo lobushushu eliphakamileyo, kodwa i-atomic nitrogen inokusabela ngezithambi ezininzi. kwaye ungena kwintsimbi ukwenza i-brittle witter with the ther. I-Iron, i-Aluminium, iTitanium, iChromium kunye nezinye izinto zokwabelana zinokubandakanyeka kwezi zinto zisenzileyo. Owona mthombo ophambili we-atomic nitrogen kukungalunganga kwe-ammonia. I-Ammonia Delication yenzeka kwi-Ammoyishini, i-Ammonia Reals kunye nezixhobo zokugcina iziko elisebenza nge-371 ° C ~ 593 ° C, i-otmoster ~ 15kg / mm².
Kwezi meko, i-chromium carbide ivela kwi-chromium ephantsi yentsimbi. Ingachithwa nge-atomic nitrogen kwaye ivelise i-chromium kunye nokukhululwa kwekhabhoni kunye ne-hydrogen yokuvelisa i-methane, njengoko kubhekiswa apha ngasentla, okanye enye yazo. Nangona kunjalo, kunye ne-Chromium ngaphezulu kwe-12%, ii-carbides kwezi ntaka zizizinzileyo kune-chromium, ke ukusabela kwangaphambi kokuba kwenziwe, ngoko ke izinto ezingenanto zisetyenziswa kwiindawo ezishushu ze-ammonia.
Imeko yentsimbi engenasimo eAmmonia igqitywe ngamaqondo obushushu, uxinzelelo, uxinzelelo lwegesi kunye neChromium-nikel. Iimvavanyo zentsimi zibonisa ukuba inqanaba le-corrosion (ubunzulu bentsimbi eguqulweyo okanye ubunzulu be-carburic) ye-fercitic okanye i-staints engenazinto ezingenasitali okanye izistim ezingenasiseko ziphezulu kunezona zinto zibalulekileyo. Njengoko umxholo unyusa iqondo lokungasebenzi.
Intsimbi engenasibala esingenasimo inobushushu obuphezulu i-halon vapor, i-corrosion ibaluleke kakhulu, i-fluorine ingaphezulu kune-chlorine. Kwintsimbi ephezulu ye-NI-C intsimbi engenasitali, umda ophezulu weqondo lokushisa lokufumana kwi-Famine yegesi yegesi ye-249 ℃, i-chlorine ye-316 ℃.
