Dhuumaha birta Alloy waxaa inta badan loo isticmaalaa in warshad korontada, awoodda nukliyeerka, kuleyliyaha cadaadis sare, superheater heerkulka sare iyo reheater iyo cadaadis kale oo sarreeya iyo dhuunta heerkulka sare iyo qalabka, waxa ay ka samaysan tahay bir kaarboon tayo sare leh, qaab-dhismeedka alloy steel iyo walxo kulaylka u adkaysta, by duub kulul (extrusion, ballaarinta) ama duub qabow (jiid).

Faa'iidada ugu weyn ee tubada Alloy Steel waa in dib loo warshadayn karo 100%, taas oo la jaanqaadaysa istiraatiijiyadda qaranka ee ilaalinta deegaanka, badbaadinta tamarta iyo badbaadinta kheyraadka. Siyaasadda qaranku waxay dhiirigelisaa balaadhinta goobta codsiga ee cadaadiska sare ee tuubada Alloy. Waqtigan xaadirka ah, isticmaalka tuubada daawaha ee Shiinaha ayaa ka dhigan kaliya kala bar wadarta isticmaalka birta ee wadamada horumaray. Ballaarinta duurka isticmaalka tuubada daawaha waxay siisaa meel ballaadhan oo loogu talagalay horumarinta warshadaha. Sida laga soo xigtay cilmi-baarista kooxda khabiirka ah ee Alloy Pipe Branch of China Special Steel Association, baahida loo qabo tuubooyinka daawaha cadaadiska sare ee Shiinaha ayaa kordhin doona 10-12% sanad walba mustaqbalka. habka (seamless seamless) si loo qeexo, laga soocaa tuubada tollayntu waa tuubada tollayn, oo ay ku jiraan tuubada alxanka tolida tooska ah iyo tuubada wareega.

Maaddada tuubada daawaha waa qiyaas ahaan sida soo socota:

16-50Mn, 27SiMn, 40Cr, 12-42CrMo, 16Mn, 12Cr1MoV, T91, 27SiMn, 30CrMo, 15CrMo, 20G, Cr9Mo, 10CrMo910, 15Mo5Cr, 15Mo3 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 50Cr, 45CrNiMo, iwm.
