310S Stainless Steel
I-Stainless Steel 310S iphakeme-i-chromium,{2}}iphezulu{2}}i-nickel austenitic stainless steel edume ngokuhlukile{3}}ukumelana ne-oxidation yezinga lokushisa eliphezulu kanye nokuzinza okuphakeme kwemishini ngaphansi kwezimo ezishisayo ezishisayo. Njengokwehluka kwekhabhoni ephansi{{5}yebanga le-310, yakhelwe ngokukhethekile ukuthi iphumelele{7}}kusevisi yezinga lokushisa eliphezulu eqhubekayo, ikwenze kube ukukhetha okuphambili kwezinhlelo zokusebenza ezibandakanya ukuchayeka isikhathi eside ekushiseni okuphezulu nezimo ezibolayo.

Isici
I-Stainless Steel 310S ikweleta ukusebenza kwayo ngenxa yokwakheka kwayo kwamakhemikhali okuhlukile. Nge-chromium engu-24-26%, yenza isendlalelo se-oxide esivikelayo, esiqinisekisa ukumelana ne-oxidation esezingeni eliphezulu. Okuqukethwe kwe-nickel engu-19-22% kuzinzisa ukwakheka kwayo kwe-austenitic, ithuthukisa i-ductility kanye nokumelana nokukhathala okushisayo. Okuqukethwe kwekhabhoni ephansi (ubukhulu obungu-0.03%) kuvimbela imvula ye-carbide, kunciphisa izingozi zokugqwala kwe-intergranular.
Mayelana nezakhiwo zemishini, i-310S idlula amazinga okushisa. Ezimweni ze-ambient, inamandla amancane okudonsa angu-515 MPa futhi ikhiqiza amandla angu-205 MPa, nobude obungama-40% ngesikhathi sekhefu. Ngokuphawulekayo, igcina amandla nokumelana nokunyakaza ngaphezu kwe-1000 degree, idlula ontanga abaningi.
Ukumelana nokugqwala kuchaza i-310S. Imelana nokusetshenziswa okuqhubekayo kufika ku-1150℃kanye nokuchayeka ngezikhathi ezithile ku-1200℃ngaphandle kwe-oxidation eqinile. Imelana kahle ne-sulfuric atmosphere kanye nokugqwala kwezimboni, nakuba ukumelana kwayo ne-chloride pitting kufana nokungu-304. Ikhabhoni yayo ephansi ivumela ukushisela ngaphandle{6}}i-weld annealing, igcina ukumelana nokugqwala kwayo.
Izinhlelo zokusebenza
I-Ultra-Izithando zokushisa eziphakeme zezimboni: Amakamelo omlilo, amashubhu akhazimulayo, izinto zokulungisa ukushisa (zimelana kufika ku-1200℃);
Imishini yokuqhekeka ye-Petrochemical:amashubhu aqhekeka i-ethylene, amashubhu aguqulayo;
Amandla namandla:Ama-incinerator linings, amashubhu okuvikela i-thermocouple;
Imboni yengilazi ne-ceramic:Izesekeli zokuncibilika kweziko, isikhunta.
Amashadi ashisayo: 310s insimbi engagqwali, China 310s abakhiqizi bensimbi engagqwali, abahlinzeki, imboni
