Ukusetshenziswa kwezimboniinsimbi engagqwalingokusho kwenhlangano ye-metallographic ingahlukaniswa ngezigaba ezintathu: insimbi engagqwali ye-ferritic, insimbi engagqwali ye-martensitic, insimbi engagqwali ye-austenitic.Kungaba izici zalezi zinhlobo ezintathu zensimbi engagqwali (njengoba kukhonjisiwe etafuleni elingezansi), kodwa kufanele kuqashelwe ukuthi insimbi engagqwali martensitic akuzona zonke ayikwazi ashiselwe, kodwa kuphela izimo ezithile, ezifana Welding kufanele kube. preheated emva Welding kufanele izinga lokushisa eliphezulu intukuthelo ukuze inqubo Welding iyinkimbinkimbi.Ukukhiqizwa kwangempela kwensimbi engagqwali ye-martensitic efana ne-1Cr13, 2Cr13 ne-2Cr13 kanye ne-45 steel welding noma ngaphezulu.

I-Ferritic insimbi engagqwali futhi ingeyensimbi engagqwali ye-chrome
Okuqukethwe kwekhabhoni ephansi, i-anti-atmospheric, i-nitric acid ne-saline solution corrosion ikhono, izinga lokushisa eliphezulu ukumelana ne-oxidation nokunye.Ikakhulukazi esetshenziselwa ukukhiqizwa kwemishini yamakhemikhali esitsheni, ipayipi.

Insimbi engagqwali ye-Austenitic iyinsimbi engagqwali ye-chrome nickel
Inokumelana nokugqwala okuphezulu, i-plasticity enhle kakhulu, i-weldability enhle kanye nokuqina kokushisa okuphansi, ayinawo kazibuthe, kulula ukusebenza kanzima.Isetshenziswa kakhulu emisebenzini yemidiya ebolayo ezingxenyeni, iziqukathi, amapayipi, okokusebenza kwezokwelapha kanye nemvelo elwa nozibuthe.
