ASTM A335 Alloy Steel Dhuumaha aan Xumaan lahayn

ASTM A335 Alloy Steel Tubooyin aan Xumaan lahayn Sawirka

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.

Daawaynta kulaylka

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.

Shuruudaha Imtixaanka

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 koronto ee aan burburin waa ikhtiyaari.
