| Lub zog tensile | Lub Zog Tawm | Kev ntev | |
| ASTM A335 P92 | 90 ksi [620 MPa] feeb | 64 ksi [440 MPa] feeb | 20% feeb (Ntev) |
ASTM A335 teev cov nqi elongation tsawg kawg nkaus rau P92 rau txhua 1/32 nti [0.8 hli] txo qis hauv phab ntsa tuab.
| Phab ntsa tuab | P92 Kev ntev hauv 2 nti lossis 50 hli | |
| in | mm | Ntev ntev |
| 0.312 | 8 | 20% feeb |
| 0.281 | 7.2 | 19 % feeb |

Qhov twg phab ntsa tuab nyob nruab nrab ntawm ob tus nqi saum toj no, tus nqi elongation tsawg kawg nkaus yog txiav txim siab los ntawm cov qauv hauv qab no:
E = 32t + 10.00 [E = 1.25t + 10.00]
Qhov twg:
E = elongation hauv 2 nti lossis 50 hli, %, thiab
t = qhov tuab tiag tiag ntawm cov qauv, hauv. [hli].
Cov Kev Cai Rau Qhov Nyuaj

| Brinell | Vickers | Rockwell | |
| ASTM A335 P92 | 250 HBW siab tshaj | 265 HV siab tshaj | 25 HRC siab tshaj |
Rau cov kav dej uas muaj phab ntsa tuab 0.200 nti [5.1 hli] lossis ntau dua, yuav tsum siv qhov kev xeem Brinell lossis Rockwell hardness.
Kev ntsuam xyuas Vickers hardness yuav tsum ua raws li Txoj Kev Xeem E92.
Kev Ntsuas Kom Sib Nqus
Cov kev ntsuam xyuas yuav tsum tau ua rau cov qauv coj los ntawm ib kawg ntawm cov yeeb nkab raws li cov kev cai ntawm Tshooj 20 ntawm ASTM A999.
Kev Ntsuas Khoov
Rau cov yeeb nkab uas muaj txoj kab uas hla tshaj NPS 25 thiab uas nws txoj kab uas hla mus rau phab ntsa tuab yog 7.0 lossis tsawg dua yuav tsum raug rau qhov kev sim khoov es tsis txhob sim ua kom tiaj tus.
Cov qauv kuaj khoov yuav tsum tau khoov ntawm chav tsev kub txog 180 ° yam tsis muaj tawg rau sab nraud ntawm qhov khoov.
Chaw Tsim Khoom thiab Mob
ASTM A335 P92 cov kav hlau yuav tsum tau ua los ntawmcov txheej txheem tsis muaj teeb meemthiab yuav tsum yog kub tiav los yog txias kos, raws li tau teev tseg.
Cov yeeb nkab tsis muaj qhov txuas yog cov yeeb nkab uas tsis muaj qhov txuas. Hauv qhov kub thiab txias thiab siab, cov yeeb nkab tsis muaj qhov txuas tuaj yeem tiv taus qhov siab thiab kub sab hauv siab dua, muab kev ruaj khov zoo dua thiab cov khoom siv kho tshuab, thiab zam kev puas tsuaj ntawm cov xov txuas.
Kev Kho Mob Kub
Cov yeeb nkab P92 yuav tsum tau rov ua kom sov rau kev kho cua sov thiab kho raws li qhov yuav tsum tau ua.
| Qib | ASTM A335 P92 |
| Hom Kho Mob Kub | normalizes thiab txo qhov mob |

Qee cov hlau ferritic uas tau npog los ntawm cov lus qhia no yuav tawv yog tias txias sai sai los ntawm qhov kub siab tshaj qhov kub tseem ceeb. Qee qhov yuav tawv los ntawm huab cua, uas yog, tawv mus rau qib tsis xav tau thaum txias hauv huab cua los ntawm qhov kub siab.
Yog li ntawd, kev ua haujlwm uas cuam tshuam nrog kev ua kom sov cov hlau no siab dua lawv qhov kub tseem ceeb, xws li kev vuam, flanging, thiab kev khoov kub, yuav tsum tau ua raws li kev kho cua sov tsim nyog.
