Umbhobho wentsimbi engenamthungo we-alloy sisixhobo esisebenza kakuhle esisetyenziswa kakhulu kushishino nasekwakhiweni. Eyona nto iphambili kukuphucula iipropati zoomatshini, ukumelana nokugqwala kunye nokumelana nobushushu obuphezulu kwemibhobho yentsimbi ngokongeza izinto ezahlukeneyo ze-alloy, ezifana ne-chromium, i-molybdenum, i-nickel, njl. Ezi zilandelayo zezinye zezinto eziqhelekileyo zepayipi yentsimbi engenamthungo ye-alloy:

I-ASTM A335Uthotho lwe-P:

P5: Umbhobho wentsimbi we-P5 uqulethe i-5% ye-chromium kunye ne-0.5% ye-molybdenum, unokumelana okuhle kwe-oxidation kunye namandla obushushu aphezulu, kwaye uhlala usetyenziswa kwimibhobho yomphunga obushushu obuphezulu kunye nomzi-mveliso we-petrochemical.
P9: Umbhobho wentsimbi we-P9 uqulethe i-9% ye-chromium kunye ne-1% ye-molybdenum, unokumelana okuphezulu kwe-oxidation kunye nokumelana nokugqwala kune-P5, kwaye ufanelekile kwindawo enobushushu obuphezulu kunye noxinzelelo oluphezulu.
P11: Umbhobho wentsimbi we-P11 uqulethe i-1.25% ye-chromium kunye ne-0.5% ye-molybdenum, usebenza kakuhle kakhulu, kwaye usetyenziswa kakhulu kwiibhoyila ezinobushushu obuphezulu kunye nezitshintshi zobushushu.
P22: Umbhobho wentsimbi we-P22 uqulethe i-2.25% ye-chromium kunye ne-1% ye-molybdenum, unamandla aphezulu obushushu kunye nokumelana ne-oxidation, kwaye uhlala usetyenziswa kwimibhobho yobushushu obuphezulu kunye noxinzelelo oluphezulu kwizityalo zamandla kunye nomzi-mveliso we-petrochemical.
I-P91: Umbhobho wentsimbi we-P91 yintsimbi ye-chromium ephezulu kunye ne-molybdenum ephezulu, equlethe i-9% ye-chromium kunye ne-1% ye-molybdenum, kwaye ine-trace amounts ye-vanadium kunye ne-nitrogen. Inamandla aphezulu obushushu kunye namandla okuhamba kwaye isetyenziswa kakhulu kwizityalo zamandla ezibaluleke kakhulu nezibaluleke kakhulu.
I-ASTM A213Uthotho lwe-T:

T11: Umbhobho wentsimbi we-T11 uqulethe i-1.25% ye-chromium kunye ne-0.5% ye-molybdenum, efana ne-P11, kwaye isetyenziswa kakhulu kwi-heat exchangers kunye nee-boilers ezinobushushu obuphezulu.
T22: Umbhobho wentsimbi we-T22 uqulethe i-2.25% ye-chromium kunye ne-1% ye-molybdenum, efanelekileyo kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye isetyenziswa kakhulu kwizityalo zamandla kunye namashishini e-petrochemical.
T91: Umbhobho wentsimbi we-T91 ufana nowe-P91, oqulethe i-9% ye-chromium kunye ne-1% ye-molybdenum, kwaye une-vanadium kunye ne-nitrogen. Unamandla aphezulu obushushu kunye nokumelana nokuqhekeka kwaye ufanelekile kwizityalo zamandla ezibaluleke kakhulu kunye nezibaluleke kakhulu.
EN 10216-2:
10CrMo9-10: Lo ngumbhobho wentsimbi ye-alloy esemgangathweni yaseYurophu equlethe i-chromium kunye ne-molybdenum, enamandla aphezulu obushushu kunye nokumelana nokugqwala, osetyenziswa kakhulu kwizityalo zamandla kunye namashishini e-petrochemical.
Iipayipi zentsimbi ezingenamthungo ze-alloy ziphucula kakhulu ukusebenza okubanzi kweepayipi zentsimbi ngokongeza izinto ezithile ze-alloy kwintsimbi, kwaye zifanelekile kwiimeko ezahlukeneyo zokusebenza eziqatha. Iipayipi zentsimbi ze-P series kunye ne-T series ezine-chromium ephezulu kunye ne-molybdenum ephezulu, ezifana ne-P91 kunye ne-T91, zimele indlela yophuhliso lwezixhobo zanamhlanje zobushushu obuphezulu kunye noxinzelelo oluphezulu kwaye zisetyenziswa kakhulu kwizityalo zamandla ezibaluleke kakhulu nezibaluleke kakhulu. Ukukhetha izixhobo zepayipi zentsimbi ezingenamthungo ze-alloy ezifanelekileyo akunakuqinisekisa kuphela ukhuseleko kunye nokusebenza okuzinzileyo kweprojekthi, kodwa kukwaphucula kakhulu ubomi benkonzo kunye nokusebenza kakuhle kwezixhobo.
