Saxanka birta ah waxa uu leeyahay dusha siman, caag sare, adkaanta iyo xoogga farsamada, waana u adkaysta daxalka aashitada, gaaska alkaline, xalalka iyo warbaahinta kale. Waa nooc ka mid ah birta daawaha ah oo aan fududayn in miridhku ku jiro, laakiin gebi ahaanba ma aha mid miridhkiisu xor yahay. Saxanka birta ah waxaa loola jeedaa saxanadda birta ah ee u adkeysata daxalka warbaahinta daciifka ah sida jawiga, uumiga iyo biyaha, halka saxanka birta u adkeysaneysa aashitada loola jeedo saxanka u adkaysta daxalka kiimikada etching media sida acid, alkali iyo milixda. Saxan birta aan-dhalatada lahayn waxay leedahay taariikh in ka badan hal qarni tan iyo markii ay soo baxday horraantii qarnigii 20aad.
Saxanka birta-la'aanta ah guud ahaan waa magaca guud ee saxanka birta ah iyo saxan birta u adkaysata aashitada. Waxay soo baxday bilowgii qarnigan. Horumarinta saxanka birta ah ayaa dhigay qalab muhiim ah iyo aasaas farsamo oo loogu talagalay horumarinta warshadaha casriga ah iyo horumarka sayniska iyo tignoolajiyada. Waxaa jira noocyo badan oo ah taarikada birta ah oo aan lahayn astaamo kala duwan. Waxay si tartiib tartiib ah u sameysay dhowr qaybood oo geedi socodka horumarka. Marka loo eego qaab-dhismeedka, waxa loo qaybiyaa afar qaybood: austenitic ahama saxan, Martensitic ahama saxan (oo ay ku jiraan roobab adag saxan bir ahama), saxan bir ferritic ahama, iyo austenitic iyo ferritic duplex ahama birta saxan? Marka loo eego isku dhafka kiimikada ugu weyn ee saxanka birta ama qaar ka mid ah walxaha astaamaha ah ee saxanka birta, waxay u qaybsantaa saxan bir ah oo aan lahayn chromium, chromium nickel saxan bir ah, chromium nickel molybdenum saxan bir-yar, saxan bir ahama, saxan bir ahama-nadiifin sare-sare, iwm. Marka loo eego sifooyinka waxqabadka iyo isticmaalka taarikada birta, waxay u qaybsan yihiin nitric acid saxan bir ahama u adkaysta, sulfuric acid u adkaysta saxan bir ahama, godad daxalka u adkaysta saxan bir ahama, stress daxalka u adkaysta saxan bir ahama, iwm. Saxan birta aan magnetic-ka ahayn, goynta bilaashka ah ee saxan birta ah, saxan bir ah oo superplastic ah, iwm. Waqtigan xaadirka ah, habka loo isticmaalo kala soocidda inta badan waa in loo kala saaro saxanka birta sida waafaqsan sifooyinka qaab-dhismeedka ee saxanka birta, sifooyinka kiimikada ee saxanka birta iyo isku dhafka labada. Guud ahaan waxa loo qaybiyaa saxan bir ahama martensitic, ferritic ahama saxan, austenitic ahama saxan, saxan birta duplex iyo roobab adag oo saxan bir ahama, ama saxan bir ahama chromium iyo saxan bir nikkel. Isticmaalka caadiga ah: qalabka saxarada iyo waraaqaha, kulaylka, qalabka farsamada, qalabka rinjiyeynta, qalabka filimaanta, dhuumaha, alaabta dibadda ee dhismayaasha xeebaha, iwm.
