Isticmaalka warshadahaBir daxal laheynSida laga soo xigtay ururka metallographic waxaa loo qaybin karaa saddex qaybood: birta birta ah ee ferritic, martensitic ahama, austenitic ahama.Waxay noqon kartaa sifooyinka saddexdan nooc ee birta ah (sida ku cad jaantuska hoose), laakiin waa in la ogaadaa in birta birta ah ee martensitic aysan ahayn dhammaan kuwa aan la isku dhejin karin, laakiin kaliya shuruudo gaar ah, sida alxanka waa in la sameeyaa. preheated alxanka ka dib waa inuu ahaadaa mid heerkul sare leh si habka alxanka uu u sii adag yahay.Wax soo saarka dhabta ah ee qaar ka mid ah birta martensitic ahama sida 1Cr13, 2Cr13 iyo 2Cr13 iyo 45 birta alxanka ama ka badan.

Birta aan lahayn Ferritic sidoo kale waxaa iska leh birta aan chrome-ka lahayn
Waxyaabaha kaarboonka hooseeya, anti-atmospheric, nitric acid iyo awoodda daxalka milixda, caabbinta oksaydhka heerkulka sare iyo wixii la mid ah.Inta badan loo isticmaalo soo saarista qalabka kiimikada ee weelka, tuubada.

Austenitic steel waa bir aan lahayn nikkel chrome
Leh iska caabin daxalka sare leh, caag aad u fiican, alxanka wanaagsan iyo adkaanta heerkulka hooseeya, ma laha magnet, fududahay in la shaqeeyo.Inta badan loo isticmaalo shaqada warbaahinta daxalaysa qaybo, weelasha, tuubooyinka, qalabka caafimaadka iyo deegaanka anti-magnetic.
