ASTM A213 T91(ASME SA213 T91) inowanzoshandiswa ferritic alloy seamless simbi pombi ine 8.0% kusvika 9.5% Cr, 0.85% kusvika 1.05% Mo, uye zvimwe microalloying zvinhu.
Aya alloying ekuwedzera anopa T91 simbi machubhu ane yakanakisa-tembiricha simba, creep resistance, uye oxidation resistance, zvichiita kuti zvishandiswe zvakanyanya mumaboilers, superheaters, uye heat exchangers inoshanda pasi pehutembiricha hwepamusoro uye nekudzvanywa.
Nhamba yeUNS: K90901.
T91 simbi mapaipi anogona kuiswa muzvikamuType 1uyeType 2, nemusiyano mukuru uri kugadziridzwa kudiki mukugadzirwa kwemakemikari.
Rudzi rwechipiri rune zvakanyanya zvinodiwa zvemakemikari zvinhu; semuenzaniso, zvinyorwa zveS zvakaderedzwa kubva pahuwandu hwe0.010% muRudzi rwekutanga kusvika pahuwandu hwe0.005%, uye miganho yepamusoro nepasi yezvimwe zvinhu inogadziriswawo.
Type 2 inonyanya kuitirwa zvakanyanya kudiwa zvakanyanya-tembiricha kana corrosive nharaunda, zvichipa kusimba kwakagadziridzwa uye kuramba.
Tevere, ngatitarisei zvakanyanya izvo zvinodikanwa zvekuumbwa kwemakemikari kune Type 1 uye Type 2 mukuongorora kwechigadzirwa.
