ASTM A335 Alloy Alloy bir daawaha hoose ee tuubada birta ah ee aan fiicneyn
Sharaxaad Gaaban:
ASTM A335 waxaa badanaa loogu yeeraa biibito chrome moly sababtoo ah kiimikooyinka ka kooban Molybdenum (Mo) iyo Chromium (Cr).Molybdenum waxay kordhisaa xoogga birta iyo Chromium (ama chrome) waa xubinta lama huraanka ah ee birta aan-ka-baxa lahayn.Tuubbada birta ah ee ka kooban chrome moly alloy waxay ka dhigaysaa mid ku habboon in loo isticmaalo warshadaha tamarta, warshadaha sifaynta, dhirta kiimikada batroolka, iyo adeegyada goobta saliidda halkaasoo dareeraha iyo gaasaska lagu qaado heerkul aad u sarreeya iyo cadaadis.

Iska caabin xoog leh oo dillaaca heerkulka sare iyo cadaadiska sare.
Waxa loo isticmaali karaa Adeegyada Daxalka Hydrogen Sulfide.
U adkaysta dildilaaca ka imanaya weerarka Haydaroojiin iyo qallafsanaan.
U adkaysta dildilaaca daxalka sulfide ee kulul.
Waxa loo isticmaali karaa Codsiyada NACE halkaas oo bay'ada dhanaantu ay ku hoos jiraan kulayl sare iyo cadaadis.
Waxa lagu isticmaali karaa NACE-MRO 175 Adeegga Dhadhanka.
Ku habboon codsiyada dillaaca gurguurta.
Wuxuu xamili karaa heerkulka sare leh dabacsanaan aad u hooseeya.
Noocyada birta daawaha ah ee ay dabooshay ASTM A335 - ASME SA335 qeexida waxaa loogu talagalay horgalaha "P", laga bilaabo P5 ilaa P92.Fasalada P11/P22 iyo P91/92 ayaa sida caadiga ah laga helaa xarumaha korontada, halka fasalka P5 iyo P9 ay aad ugu badan yihiin codsiga warshadaha petrochemical.Fasalada P9, P91, liiska, waa kuwa ka qaalisan

Demisay iyo Xanaaqa.
Caadiyan & Adkeynta.
Transverse/longitudinal: kacsanaan iyo fidsanaan, qallafsanaan, imtixaanada qaloocsanaan- alaabta lagu daaweeyay kulaylka foornooyinka dufcada, tijaabooyinkan waa in lagu sameeyaa 5% tuubooyinka nambar kasta oo kulaylka ah.Qaybaha yaryar, hal tubo ugu yaraan waa in la tijaabiyaa.
ASTM A335 Gr.P91 waa in ay lahaataa adkaanta 250 HB/265 HV (25 HRC).
Baaritaanka biyaha: waa in lagu dabaqaa dherer kasta oo tuubo ah.
Tijaabada korantada ee aan burburin waa ikhtiyaari.
