Alloy bir bir ah & go'yaal & xirmooyin
Ista'oorta aloy waa bir ay bir bir ah oo leh walxo kala duwan oo wadarta guud ee u dhexeeya 1.0% iyo 50% miisaanka si loo wanaajiyo hantida farsamada. Stels stels waxaa loo kala jabay laba kooxood: stors-ka hoose ee alfoonka yar iyo stores-ka sare ee loo yaqaan 'potoy'. Farqiga u dhexeeya labada waa la muransan yahay. Smith iyo Hashemi ayaa qeexaya farqiga u dhexeeya 4.0%, halka Degardo, et al., Qeexdaa boqolkiiba 8.0%. [1] [2] Inta badan, weedha "aloy bir" waxaa loola jeedaa stors-ka yar-yar.
ASTM A335 waa tilmaanta caadiga ah ee loogu talagalay shahaadada xasaasiga ah ee xarkaha birta birta ee loo yaqaan 'pipe' bir ah oo heerkulka sare ah. Covers server levels: P1, P2, P5, P5b, P5c, P9, P11, P12, P15, P21, P22, P23, P91, P92, P122, of which P5, P9, P11, P22, P91, P92 are used in practice the most extensive. Sideyntani waxay daboolaysaa magacaabista iyo kan ugu yar ee darbiga-molybdenum (oo sidoo kale loo yaqaan cr-mol mo ama moly) birta birta birta ee aswiifeedka ugu hooseeya ee codsiyada heerkulka sare. Tuubbada lagu amro in la caddeeyo ayaa ku habboon foorarsiga, qalliinka la midka ah iyo qaab dhismeedka la midka ah, iyo alxanka dhexda. ASTM A335 P11, P22, P91 iyo P92 iyo P92 waxaa badanaa loo adeegsadaa dhirta korantada iyo warshadaha kiimikada iyo patrochemical iyo p5 inta badan waxaa loo isticmaalaa nadiifinta saliida.
ASTM A3355 PIPE Fasalka Fasalka P91 waa tuubo tayo sare leh oo loogu talagalay kuleylka cadaadiska badan. P91 Tuubbada ayaa ku habboon in la foorarsado, garaacis ama alxamida iyo hawlgallada la midka ah. Maaddada birta waa inay u hogaansamaan shuruudaha ka kooban kiimikaad, sifooyinka khafiifka ah iyo adkaanta.
