ASTM A335 Alloy birta 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.
Waxaan diyaar u nahay inaan wadaagno aqoontayada xayeysiinta adduunka oo dhan waxaanan kugula talineynaa alaab ku habboon qiimaha iibinta gardarrada ah.Markaa Aaladaha Profi waxay ku siinayaan qiimaha lacagta ugu fiican waxaanan diyaar u nahay inaan si wadajir ah u soo saarno ASTM A335Alloy birta birta ah ee tuubada ah, Tayadu waa nolosha warshadda , Diirada saar baahida macaamiisha waa isha badbaadada iyo horumarka shirkadda

Alloy Steel tuubooyinka waxaa lagu daaweeyaa kulaylka si loo gaaro sifooyinka farsamada sida ku cad walxaha alloying ee la doonayo.Hoos waxaa ku yaal qaar ka mid ah noocyada daaweynta kulaylka.
Caadiye Quench iyo xanaaq.
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.
