Ipayipi le-alloy kanye nepayipi elingenamthungo zombili zinobudlelwano nomehluko, azikwazi ukudideka. Ipayipi le-alloy liyipayipi lensimbi ngokuhambisana nezinto zokukhiqiza (okungukuthi, izinto) ukuchaza, njengoba igama lisikisela lenziwe ngepayipi le-alloy; Ipayipi elingenamthungo lichazwa ngokuhambisana nenqubo yokukhiqiza (engenamthungo) yepayipi lensimbi, elihlukile kunepayipi elingenamthungo elihlanganisiwe, kufaka phakathi ipayipi elihlanganisiwe eliqondile kanye nepayipi elijikelezayo.

Ipayipi lensimbi ye-alloy ye-A335P5 lingelapayipi le-alloy lisetshenziswa kakhuluibhoyila yokucindezela okuphansi nokuphakathi(ingcindezi yokusebenza ngokuvamile ayidluli ku-5.88Mpa, izinga lokushisa lokusebenza lingaphansi kuka-450℃) ipayipi lokushisa elingaphezulu; Isetshenziselwaibhoyila yomfutho ophezulu(ingcindezi yokusebenza ngokuvamile ingaphezu kuka-9.8Mpa, izinga lokushisa lokusebenza liphakathi kuka-450℃ ~ 650℃) ipayipi lokushisa elingaphezulu, i-economizer, i-superheater, i-reheater, ipayipi lemboni ye-petrochemical, njll.

Ezinye izinto yilezi: 16-50Mn、27SiMn、40Cr、Cr5Mo、12Cr1MoV、12Cr1MovG、15CrMo、15CrMoG、15CrMoV、13CrMo44、T91、27SiMn、25CrMo、30CrMo、35CrMo、35CrMoV、40CrMo、45CrMo、Cr9Mo、10CrMo910、15Mo3、A335P11、P22、P91、T91.
