321H Insimbi Engagqwali
I-321H iyinsimbi ephezulu{{1}yekhabhoni, i-titanium{2}}eqinile i-austenitic stainless steel (UNS S32109), eyakhelwe isevisi yezinga lokushisa eliphakeme. Ukwakheka kwayo kuhlanganisa u-17.0-19.0% Cr, 9.0-12.0% Ni, ubuncane obungu-0.15% Ti, nekhabhoni elawulwa ku-0.04-0.10%—iphezulu kune-321 evamile.
Ikhabhoni ekhuphukile ithuthukisa-amandla ezinga lokushisa eliphezulu kanye nokumelana nokuphuka, okubalulekile ekusebenzeni okuzinzile ku-650-900℃. I-Titanium iyazinza ngokumelene nemvula ye-carbide, iqeda ukugqwala kwe-intergranular ezindaweni ezishiselwe/ezithinteke ukushisa.

Isici
I-321H iwuhlobo oluphezulu-lwekhabhoni (0.04%~0.10% C) lwensimbi engagqwali engu-321, ethuthukiswe ngokukhethekile-isevisi yezinga lokushisa eliphezulu. Ngenkathi igcina izici ezibalulekile ze-321, ifinyelela ukumelana okuhlanganisiwe kokugqwala kwe-intergranular kanye namandla athuthukisiwe{8}}ezinga lokushisa eliphezulu ngokulawulwa kokuqukethwe kwekhabhoni ephezulu kanye nokuzinza kwe-titanium.
Izinhlelo zokusebenza
{{0}Izingxenye Zengcindezi Yezinga Lokushisa Eziphezulu Zezimo Ezidlulele:
I-Aerospace:Amapayipi okukhipha amandla enjini yendiza, ama-boiler superheaters ({0}}isevisi yesikhathi eside ngaphansi kuka-800℃)
Amasistimu we-Petrochemical:Amashubhu esithandweni somlilo,{0}}ama-reactor aphezulu
Isisetshenziswa Sokucubungula Okushisayo:Amarola okushisa okushisa,{0}}izinto zokubopha izinga lokushisa eliphezulu
Amashadi ashisayo: 321h insimbi engagqwali, China 321h abakhiqizi bensimbi engagqwali, abahlinzeki, imboni
