ASTM A335 P92 (ASME SA335 P92) waa tuubo bir ah oo aan kala go 'lahayn oo loogu talagalay adeeg heerkul sare leh.Magaca UNS waa K92460.
P92 waa bir bir ah oo kulaylka u adkaysta oo chromium sare leh oo ka kooban 8.50–9.50% chromium waxaana lagu dahaadhay Mo, W, V, iyo Nb, taasoo bixisa xoog heer sare ah oo heerkul sare ah, iska caabin oksaydh, iyo iska caabin daal kuleyl.
Waxaa si weyn loogu isticmaalaa khadadka uumiga ugu muhiimsan, dib u kululaynta khadadka uumiga, tuubooyinka kululeeyaha iyo dib u kululeeyaha ee kuleyliyaha awoodda sare iyo kuwa aadka u daran, iyo sidoo kale tuubooyinka habka heerkulka sare, cadaadiska sare iyo qaybaha muhiimka ah ee haynta cadaadiska ee xarumaha batroolka iyo sifeynta.
Botop Steel waa shirkad xirfadle ah oo lagu kalsoonaan karo oo iibisa tuubooyinka birta ee birta ah ee Shiinaha, oo awood u leh inay si dhakhso ah mashaariicdaada ugu keento noocyo kala duwan oo tuubooyin bir ah oo bir ah, oo ay ku jiraanP5 (K41545), P9 (K90941), P11 (K11597), P12 (K11562), P22 (K21590), iyoP91 (K90901).
Alaabooyinkeenu waa tayo la isku halleyn karo, qiimo tartan leh, waxayna taageeraan kormeerka dhinac saddexaad.

ASTM A335 waxay qeexaysaa qiimayaasha ugu yar ee la xisaabiyay ee P92 ee 1/32 inji kasta [0.8 mm] oo ah hoos u dhac ku yimaada dhumucda derbiga.

Meesha dhumucda derbigu ay u dhaxayso laba qiime oo kor ku xusan, qiimaha ugu yar ee fidinta waxaa lagu go'aamiyaa qaacidada soo socota:
E = 32t + 10.00 [E = 1.25t + 10.00]
Halkee:
E = fidinta 2 inji ama 50 mm, %, iyo
t = dhumucda dhabta ah ee muunadaha, gudaha [mm].
Shuruudaha Adkaanta

| Brinell | Vickers | Rockwell | |
| ASTM A335 P92 | 250 HBW ugu badnaan | 265 HV ugu badnaan | 25 HRC ugu badnaan |
Tuubooyinka leh dhumucda derbigu waa 0.200 inji [5.1 mm] ama ka badan, waa in la isticmaalaa tijaabada adkaanta Brinell ama Rockwell.
Tijaabada adag ee Vickers waa in lagu sameeyaa iyadoo la raacayo Habka Tijaabada E92.
Imtixaanka Fiditaanka
Tijaabooyinka waa in lagu sameeyaa muunado laga soo qaaday hal dhinac oo tuubada ah iyadoo la raacayo shuruudaha Qaybta 20aad ee ASTM A999.
Imtixaanka Laabista
Tuubada dhexroorkeedu ka badan yahay NPS 25 oo dhexroorkeedu yahay saamiga dhumucda derbiga 7.0 ama ka yar waa in lagu sameeyaa tijaabada qallooca halkii laga isticmaali lahaa tijaabada siman.
Shaybaarada tijaabada qallooca waa in lagu qaloociyaa heerkulka qolka ilaa 180° iyada oo aan dildilaac ka dhicin dibadda qaybta qalloocan.
Soo-saaraha iyo Xaaladda
Tuubooyinka birta ah ee ASTM A335 P92 waa in laga sameeyaa iyadoo la adeegsanayogeeddi-socod aan kala go 'lahaynwaana in lagu sameeyaa qaab kulul ama mid qabow, sida ku cad.
Tuubo aan kala go 'lahayn waa tuubo aan lahayn alxan. Deegaannada heerkulka sare iyo cadaadiska sare leh, tuubooyinka aan kala go'a lahayn waxay u adkeysan karaan cadaadis gudaha iyo heerkulka sare, waxay bixiyaan hufnaan qaab-dhismeed oo wanaagsan iyo sifooyin farsamo, waxayna ka fogaan karaan cillado suurtagal ah oo ku yimaada tolmada alxanka.
Daaweynta Kulaylka
Tuubada P92 waa in dib loo kululeeyaa si loogu daweeyo kulaylka loona daaweeyaa si waafaqsan shuruudaha.
| Fasal | ASTM A335 P92 |
| Nooca Daaweynta Kulaylka | caadi u noqo oo dabeecad samee |
| Heerkulka Caadiga ah | 1900 ~ 1975 ℉ [1040 ~ 1080 ℃] |
| Heerkulka Qaboojinta | 1350 ~ 1470 ℉ [730 ~ 800 ℃] |
Qaar ka mid ah birta ferritic-ga ah ee lagu daboolay qeexitaankan ayaa adkaan doona haddii si degdeg ah looga qaboojiyo heerkulkooda muhiimka ah. Qaarkood waxay u adkaan doonaan hawada, taas oo ah, inay adkaadaan ilaa heer aan loo baahnayn marka lagu qaboojiyo hawada heerkul sare awgiis.
Sidaa darteed, hawlgallada ku lug leh kululaynta birta noocaas ah heerkulkooda muhiimka ah, sida alxanka, flanging, iyo leexashada kulul, waa in lagu daraa daaweyn ku habboon.
