25Cr2MoVA xaashi bir duuban oo kulul

① Labada nambar ee bilowga nambarka birta waxay muujinayaan kaarboonka birta, oo lagu muujiyey toban kun ee celceliska kaarboonka, sida 40Cr, 25Cr2MoVA tube alloy
②Waxyaabaha Alloying-ga ugu muhiimsan ee birta, marka laga reebo curiyayaasha microalloying shaqsi, waxaa guud ahaan lagu muujiyey in dhowr boqolkiiba. Marka celceliska nuxurka daawaha uu ka yar yahay 1.5%, guud ahaan kaliya calaamadda curiyaha ayaa lagu muujiyey lambarka birta, ka koobanna lama tilmaamin. Si kastaba ha ahaatee, duruufaha gaarka ah, way fududahay in la sameeyo jahawareer, lambarka "1" sidoo kale waxaa lagu calaamadin karaa calaamadda curiyaha, sida lambarka birta "12CrMoV" iyo "12Cr1MoV", kii hore wuxuu leeyahay maaddo chromium ah 0.4-0.6 %, kan dambe waxa uu ka kooban yahay chromium 0.9-1.2%, inta soo hadhayna waa isku mid. Marka celceliska waxyaabaha ku jira walxuhu ay yihiin ≥1.5%, ≥2.5%, ≥3.5%… , 18Cr2Ni4WA.
③ Walxaha alwaaxinta sida vanadium V, titanium Ti, aluminium AL, boron B, iyo naadirka dhulka RE ee birta ah dhamaantood waa curiyayaasha microalloying. Inkasta oo waxa ku jira uu aad u hooseeyo, haddana waa in lagu calaamadeeyaa lambarka birta. Tusaale ahaan, 20MnVB birta ah. Vanadium waa 0.07-0.12%, boronkuna waa 0.001-0.005%.
④ Birta tayada sare leh ee heerka sare ah waa in lagu daraa "A" dhamaadka nambarka birta si looga sooco birta tayada sare leh ee guud.
⑤ Ujeedada gaarka ah ee daawaha qaab dhismeedka birta, nambarka birta waa la horgeeyay (ama ku lifaaqan) calaamada u taagan ujeedada birta. Tusaale ahaan, birta 30CrMnSi gaar ah oo loogu talagalay birta birta ah, nambarka birta waxaa lagu muujiyay ML30CrMnSi.
Tuubooyinka daawaha iyo tuubooyinka aan xidhnayn labaduba waa isku xidhan yihiin waana kala duwan yihiin, mana aha in la jahawareeriyo.
Tuubbada Alloy waxaa lagu qeexaa birta birta ah iyadoo loo eegayo alaabta wax soo saarka (taas oo ah, walxo), sida magacu tilmaamayo, waa tuubo ka samaysan daawaha; halka dhuumaha aan kala go'a lahayn lagu qeexay birta birta ah iyadoo loo eegayo habka wax soo saarka (oo aan kala go 'lahayn), farqiga u dhexeeya tuubooyinka aan fiicneyn waa tuubooyinka Seam, oo ay ku jiraan tuubooyinka tolitaanka tooska ah iyo tuubooyinka wareega.
