Dulmarka xaashida daloolinta ee qurxinta
Biraha birta daloolsan ee daloola ayaa ah sheyga doorashada ee codsiyada waara, waxa ay leedahay iska caabin heer sare ah oo daxalka ah, waxa ay u baahan tahay dayactir yar waxayna leedahay nolol adeeg oo joogto ah.
Birta aan lahayni waa daawaha ka kooban chromium, kaas oo iska caabiya samaynta oksaydhka birta. Waxay soo saartaa filim oksaydh ah oo ku yaal dusha sare ee birta, kaas oo aan kaliya u adkaysanaynin daxalka atmospheric laakiin sidoo kale waxay siisaa siman, dusha dhalaalaya.
Marka lagu daro sifooyinka weldability, formability xoog sare iyo adkaanta sare, birta daloolin waxay ku siin kartaa wax soo saarka wax ku ool ah ee makhaayadaha iyo codsiyada processing cuntada, filtarrada aan daxaloobay iyo codsiyada dhismaha waara.

Saddex nooc oo ah xaashida birta ah ee aan daloolin
Marka loo eego qaab dhismeedka crystalline ee birta daloolin, waxaa loo kala saari karaa saddex nooc: Austenitic, Ferritic iyo Martensitic.
Birta Austenitic, oo ka kooban maaddo sare oo chromium iyo nikkel ah, waa birta u adkeysata ugu badan ee bixisa sifooyin farsamo oo aan la barbar dhigi karin, sidaas darteed, waxay noqotaa nooca ugu badan ee daawaha, xisaabinta ilaa 70% dhammaan wax soo saarka birta aan lahayn. Waa mid aan magnet-ka ahayn, kulaylna laguma dawayn karo, laakiin si guul leh ayaa loo alxan karaa, la samayn karaa, iyadoo lagu adkaynayo qabow-shaqaynta.
l Nooca 304, oo ka kooban birta, 18 - 20% chromium iyo 8 - 10% nikkel; waa darajada ugu badan ee austenitic. Waa alxanka, mashiinada codsiyada kala duwan, marka laga reebo deegaanka biyaha milixda ah.
l Nooca 316 wuxuu ka samaysan yahay birta, 16 - 18% chromium iyo 11 - 14% nikkel. Marka la barbar dhigo nooca 304, waxay leedahay iska caabin daxalka ka wanaagsan oo soo saara xoog leh alxanka iyo farsamaynta la midka ah.
l Birta Ferritic waa bir chromium toosan oo aan lahayn nikkel. Marka ay timaado iska caabin daxalka, ferritic-ku wuu ka fiican yahay darajooyinka martensitic laakiin wuu ka hooseeyaa birta aan birta lahayn ee austenitic. Waa magnetic iyo oxidation u adkaysta, sidoo kale; waxay leedahay waxqabad shaqo oo kaamil ah jawiga badda. Laakiin laguma adkeyn karo ama laguma adkeyn karo daawaynta kulaylka.
l Nooca 430 wuxuu leeyahay iska caabin sare oo u adkaysta daxalka nitric acid, gaaska sulfur, organic iyo acid acid, iwm.
