309S Insimbi Engagqwali
I-Stainless Steel 309S iphezulu-i-chromium, ephezulu-ye-nickel austenitic steel stainless steel edizayinelwe ukumelana ne-oxidation ephakeme kanye nokusebenza{3}}kwezinga lokushisa eliphezulu. Njengokwehluka okuphansi{{5}kwekhabhoni yebanga le-309, inikeza ukumelana okuthuthukisiwe kokugqwala kwe-intergranular, ikwenze ifaneleke kakhulu izinhlelo zokusebenza ezibandakanya ukuchayeka isikhathi eside kumazinga okushisa aphakeme nezimo ezishisayo ezijikelezayo.
Incazelo Yemikhiqizo
I-Stainless Steel 309S iphezulu-i-chromium, ephezulu-ye-nickel austenitic steel stainless steel edizayinelwe ukumelana ne-oxidation ephakeme kanye nokusebenza{3}}kwezinga lokushisa eliphezulu. Njengokwehluka okuphansi{{5}kwekhabhoni yebanga le-309, inikeza ukumelana okuthuthukisiwe kokugqwala kwe-intergranular, ikwenze ifaneleke kakhulu izinhlelo zokusebenza ezibandakanya ukuchayeka isikhathi eside kumazinga okushisa aphakeme nezimo ezishisayo ezijikelezayo.
Ukumelana nokugqwala kuyisici esivelele se-309S. Okuqukethwe kwayo okuphezulu kwe-chromium kunikeza ukumelana okuhle kakhulu ne-oxidation emoyeni, kuyenza ikwazi ukumelana nesevisi eqhubekayo emazingeni okushisa afika ku-980℃(1800℃F) kanye nokuchayeka ngezikhathi ezithile kufika ku-1095℃(2000℃F) ngaphandle kokukalwa okubalulekile. Inikeza ukumelana okuhle nesulfure{7}}equkethe izindawo eziningi kanye nemvelo yezimboni eziningi, nakuba ukumelana kwayo ne-chloride{8}}i-induced pitting kuqhathaniswa no-304 kune-molybdenum{10}}amabanga athuthukisiwe. Okuqukethwe kwekhabhoni ephansi kuqinisekisa ukuthi ukumelana kwayo nokugqwala kuyagcinwa ngemva kokushiselwa, okuqeda isidingo{12}}se-weld annealing ezinhlelweni eziningi.

Isici
Okuqukethwe kwe-chromium ephezulu kunika amandla ukwakheka kwesendlalelo esizinzile se-chromium oxide evikelayo emazingeni okushisa aphakeme, okuvumela ukusebenza okuqhubekayo kuze kufike ku-1150℃(isevisi yesikhashana efika ku-1035 degree). Uma kuqhathaniswa nochungechunge lwe-304, inikeza{4}}izinga lokushisa eliphezulu ukumelana ne-oxidation kanye nokumelana ne-carburization, nakuba inokumelana nokugqwala okulinganiselwe kwe-chloride. Ukwakheka okuphansi{{6}kwekhabhoni (Ngaphansi noma okulingana no-0.03%) kunciphisa ubungozi bokuzwela kwe-weld, kuyenze ifanelekele izinhlelo zokusebenza ezidinga{8}}ukuthembeka kokushisela.
Izinhlelo zokusebenza
Izingxenye Zesithando Sezimboni: Amalayini okushisa okushisa, amashubhu akhazimulayo, izingxenye zokushisa (amelana kufika ku-1100 degree)
Izisetshenziswa ze-Petrochemical:Amashubhu{0}ezinga lokushisa aphezulu aqhekekayo, izisetshenziswa zokubala
Imboni yamandla:Izisekelo ze-boiler, imigudu yomoya oshisayo
Ukusekelwa kwe-Refractory:Izesekeli zeziko lengilazi, amathuluzi e-ceramic sintering
Amashadi ashisayo: 309s insimbi engagqwali, China 309s abakhiqizi bensimbi engagqwali, abahlinzeki, ifektri
