Umbhobho wensimbi ongenamthungo we-alloy yinto ephezulu yokusebenza esetyenziswa kakhulu kwishishini kunye nokwakhiwa. Eyona nto iphambili kukuphucula iimpawu zoomatshini, ukuxhathisa umhlwa kunye nokumelana nobushushu obuphezulu bemibhobho yentsimbi ngokongeza izinto ezahlukeneyo ze-alloy, njengechromium, i-molybdenum, i-nickel, njl.

I-ASTM A335P series:

P5: Ipayipi yensimbi ye-P5 iqulethe i-5% ye-chromium kunye ne-0.5% ye-molybdenum, inokumelana ne-oxidation efanelekileyo kunye namandla aphezulu okushisa, kwaye isetyenziswa rhoqo kwimibhobho ye-steam ye-steam kunye ne-petrochemical industry.
P9: Ipayipi yensimbi ye-P9 iqulethe i-9% ye-chromium kunye ne-1% ye-molybdenum, inokumelana ne-oxidation ephezulu kunye nokumelana nokugqwala kune-P5, kwaye ifanelekile ukushisa okuphezulu kunye noxinzelelo oluphezulu.
P11: Ipayipi yensimbi ye-P11 iqulethe i-1.25% ye-chromium kunye ne-0.5% ye-molybdenum, inomsebenzi obanzi obanzi, kwaye isetyenziswa ngokubanzi kwiibhoyili zokushisa eziphezulu kunye nabatshintshi bokushisa.
P22: Ipayipi yensimbi ye-P22 iqulethe i-2.25% ye-chromium kunye ne-1% ye-molybdenum, inamandla aphezulu okushisa kunye nokumelana ne-oxidation, kwaye isoloko isetyenziselwa ukushisa okuphezulu kunye nemibhobho yoxinzelelo oluphezulu kwizityalo zamandla kunye ne-petrochemical industry.
P91: Ipayipi yensimbi ye-P91 yi-chromium ephezulu kunye ne-high molybdenum steel, equkethe i-9% ye-chromium kunye ne-1% ye-molybdenum, kwaye iqulethe ixabiso le-vanadium kunye ne-nitrogen. Inamandla obushushu obuphezulu kakhulu kunye namandla okurhubuluza kwaye isetyenziswa kakhulu kwizityalo zamandla ezigqithisileyo kunye ne-ultra-supercritical.
I-ASTM A213T series:

T11: Ipayipi yensimbi ye-T11 iqulethe i-1.25% ye-chromium kunye ne-0.5% ye-molybdenum, efana ne-P11, kwaye isetyenziswa kakhulu kwi-high heat exchangers kunye ne-boilers.
T22: Ipayipi yensimbi ye-T22 iqulethe i-2.25% ye-chromium kunye ne-1% ye-molybdenum, ifanelekile ukushisa okuphezulu kunye noxinzelelo oluphezulu, kwaye isetyenziswa ngokubanzi kwizityalo zamandla kunye namashishini e-petrochemical.
T91: Ipayipi yensimbi ye-T91 iyafana ne-P91, equkethe i-chromium eyi-9% kunye ne-1% ye-molybdenum, kwaye iqulethe i-vanadium kunye ne-nitrogen. Inamandla abalaseleyo obushushu obuphezulu kunye nokumelana nokukhasa kwaye ifanelekile kwizityalo zamandla ezigqithisileyo kunye ne-ultra-supercritical.
EN 10216-2:
I-10CrMo9-10: Lo ngumbhobho wensimbi oqhelekileyo waseYurophu oqukethe i-chromium kunye ne-molybdenum, enegunya elihle lobushushu obuphezulu kunye nokumelana nokubola, esetyenziswa ngokuqhelekileyo kwizityalo zamandla kunye namashishini e-petrochemical.
Imibhobho yensimbi engenamthungo iphucula kakhulu ukusebenza okubanzi kwemibhobho yentsimbi ngokongeza izinto ezithile ze-alloy kwintsimbi, kwaye ifanelekile kwiimeko ezahlukeneyo zokusebenza. Uchungechunge lwe-P kunye nochungechunge lwe-T lwe-chromium ephezulu kunye nemibhobho yentsimbi ye-molybdenum ephezulu, efana ne-P91 kunye ne-T91, imele isalathiso sophuhliso lobushushu obuphezulu banamhlanje kunye nezixhobo zoxinzelelo oluphezulu kwaye zisetyenziswa ngokubanzi kwizityalo zamandla ezingaphezulu kunye ne-ultra-supercritical. Ukukhetha i-alloy efanelekileyo ye-seamless steel pipe impahla ayinakuqinisekisa kuphela ukhuseleko kunye nokusebenza okuzinzile kweprojekthi, kodwa nokuphucula kakhulu ubomi benkonzo kunye nokusebenza kakuhle kwezixhobo.
