ASTM A213 T91(ASME SA213 T91) waa bir bir ah oo caadi ahaan la isticmaalo oo ka kooban 8.0% ilaa 9.5% Cr, 0.85% to 1.05% Mo, iyo walxo kale oo microalloying ah.
Wax-is-daba-marintani waxay siisaa tuubooyinka birta ee T91 oo leh awood heerkul sare oo heer sare ah, iska caabin gurracan, iyo iska caabbinta oksaydhka, taasoo ka dhigaysa in si weyn loogu isticmaalo kuleyliyaha, kulaylka sare, iyo kulaylka beddelayaasha ku shaqeeya heerkulka sare iyo xaaladaha cadaadiska sare.
Lambarka UNS: K90901.
Tuubooyinka birta ee T91 ayaa loo kala saari karaaNooca 1iyoNooca 2, iyadoo farqiga ugu weyn uu yahay hagaajin yar oo ka kooban kiimikada.
Nooca 2 wuxuu leeyahay shuruudo adag oo loogu talagalay walxaha kiimikada; tusaale ahaan, waxa ku jira S waxa laga dhimay ugu badnaan 0.010% ee Nooca 1 ah ilaa ugu badnaan 0.005%, iyo xadka sare iyo hoose ee qaybaha kale ayaa sidoo kale la hagaajiyaa.
Nooca 2 waxaa inta badan loogu talagalay heerkul sare oo aad u culus ama bey'ad daxalaysa, taasoo bixisa adkaysi soo hagaagtay iyo iska caabin gurguurta.
Marka xigta, aan si dhow u eegno shuruudaha ka kooban kiimikada ee Nooca 1 iyo Nooca 2 ee falanqaynta alaabta.

T91 Nooca 1 iyo 2 waxay leeyihiin kala duwanaansho yar oo ka kooban kiimikada, laakiin waxay wadaagaan shuruudo isku mid ah guryaha farsamada iyo daaweynta kulaylka.

Tijaabada fidsan
Habka imtixaanku waa inuu u hoggaansamaa shuruudaha khuseeya faqradda 19 ee ASTM A1016.
Hal tijaabo oo fidsan waa in lagu sameeyaa muunado laga soo bilaabo daraf kasta oo tuubo dhammaatay, oo aan ahayn kan loo isticmaalo baaritaanka ololka, qayb kasta.
Tijaabada Dhalinta
Habka imtixaanku waa inuu u hoggaansamaa shuruudaha khuseeya faqradda 22 ee ASTM A1016.
Hal tijaabo oo ifaysa waa in lagu sameeyaa shaybaar laga soo bilaabo daraf kasta oo tuubo dhammaatay, ma aha kan loo isticmaalo baadhista fiditaanka, qayb kasta.
Soo saaraha iyo Xaaladda
Tubooyinka ASTM A213 T91 waa in lagu sameeyaa habka aan kala go 'lahayn oo waa inay noqdaan kuwo kuleyl ah ama la dhammeeyey qabow, sida loo baahdo.
Tuubooyinka birta ah ee aan cillad lahayn, oo leh qaab-dhismeedkooda joogtada ah iyo alxan-la'aanta, waxay u qaybiyaan diiqada si siman oo hoos yimaada heerkulka sare, cadaadiska sare, iyo xaaladaha culeyska adag, iyagoo siinaya xoog sare, adag, iyo iska caabin daal.
Daawaynta kulaylka
Dhammaan tuubooyinka birta ee T91 waa in dib loo kululeeyaa oo lagu daaweeyaa kulayl si waafaqsan shuruudaha lagu qeexay shaxda.
Daawaynta kulaylka waa in si gaar ah loo fuliyaa iyo marka lagu daro kululaynta samaynta kulul.
| Darajo | Nooca daaweynta kulaylka | Oggolaanshaha/Daawaynta Xalka | Hoos u dhigista ama heerkulka |
| T91 Nooca 1 iyo 2 | caadiyeeyaan oo xanaaqaan | 1900 - 1975 ℉ [1040 - 1080 ℃] | 1350 - 1470 ℉ [730 - 800 ℃] |
Darajada T91 Nooca 2, daawaynta kulaylku waa in ay hubisaa in ka dib marka la hagaajiyo heerka qaboojinta 1650 °F ilaa 900 °F [900 °C ilaa 480 °C] aan ka yarayn 9 °F/min [5 °C/min].
Cabbirrada tubbada T91 iyo dhumucda gidaarada waxaa sida caadiga ah lagu rakibay dhexrooryo u dhexeeya 3.2 mm ilaa dhexroorka ka baxsan 127 mm, iyo dhumucda ugu yar ee gidaarka 0.4 mm ilaa 12.7 mm.
Cabbirrada kale ee tuubooyinka birta ee T91 ayaa sidoo kale la keeni karaa, waase la buuxiyey dhammaan shuruudaha kale ee ASTM A213.
Dulqaadyada cabbirka ee T91 waxay la mid yihiin kuwa T11. Faahfaahinta, waxaad tixraaci kartaaT11 Cabbirrada iyo Dulqaadyada.
