Ipleyiti yentsimbi engagqwaliyo ngokubanzi ligama eliqhelekileyo lepleyiti yentsimbi engagqwaliyo kunye nepleyiti yentsimbi engagqwaliyo. Ivela ekuqaleni kwale nkulungwane, uphuhliso lwepleyiti yentsimbi engagqwaliyo lubeke isiseko esibalulekileyo sezinto zobugcisa zophuhliso lwenkqubela phambili yeshishini lanamhlanje kunye nesayensi kunye netekhnoloji. Kukho iintlobo ezininzi zeepleyiti zentsimbi engagqwaliyo ezineempawu ezahlukeneyo, kwaye ziye zakha kancinci kancinci iindidi ezahlukeneyo kwinkqubo yophuhliso. Ngokwesakhiwo, yahlulwe yangamacandelo amane: ipleyiti yentsimbi engagqwaliyo ye-austenitic, ipleyiti yentsimbi engagqwali ye-martensitic (kubandakanya ipleyiti yentsimbi engagqwaliyo yemvula), ipleyiti yentsimbi engagqwali ye-ferritic, kunye nepleyiti yentsimbi engagqwali ye-austenitic ferritic duplex. Ngokwendlela eyintloko yokwakheka kwekhemikhali yepleyiti yentsimbi okanye ezinye izinto ezikwipleyiti yentsimbi ukuze zihlulwe, zahlulwe zaba yipleyiti yentsimbi engagqwali ye-chromium, ipleyiti yentsimbi engagqwali ye-chromium nickel, ipleyiti yentsimbi engagqwali ye-chromium nickel molybdenum kunye nepleyiti yentsimbi engagqwali ye-low carbon, ipleyiti yentsimbi engagqwali ye-molybdenum ephezulu, ipleyiti yentsimbi engagqwali ecocekileyo kakhulu njalo njalo. Ngokweempawu zokusebenza kunye nokusetyenziswa kwepleyiti yentsimbi, yahlulwe yaba yipleyiti yentsimbi engagqwaliyo enganyangekiyo ye-nitric acid, ipleyiti yentsimbi engagqwaliyo enganyangekiyo ye-sulfuric acid, ipleyiti yentsimbi engagqwali enomngxuma, ipleyiti yentsimbi engagqwali enganyangekiyo enganyangekiyo, ipleyiti yentsimbi engagqwali enamandla aphezulu njl. Ngokweempawu zokusebenza kwepleyiti yentsimbi, yahlulwe yaba yipleyiti yentsimbi engagqwaliyo eshushu ephantsi, ipleyiti yentsimbi engagqwali engenamagnethi, ipleyiti yentsimbi engagqwaliyo ekulula ukuyisika, ipleyiti yentsimbi engagqwali yeplastiki ephezulu. Indlela yokwahlulahlula esetyenziswa rhoqo yahlulwe ngokweempawu zesakhiwo sepleyiti yentsimbi kunye neempawu zokwakheka kweekhemikhali zepleyiti yentsimbi kunye nokudibanisa kwezi ndlela zimbini. Ngokubanzi yahlulwe yaba yipleyiti yentsimbi engagqwali ye-martensitic, ipleyiti yentsimbi engagqwali ye-ferritic, ipleyiti yentsimbi engagqwali ye-austenitic, ipleyiti yentsimbi engagqwali ye-duplex kunye nepleyiti yentsimbi engagqwali yohlobo lwemvula okanye yahlulwe yaba yipleyiti yentsimbi engagqwali ye-chromium kunye nepleyiti yentsimbi engagqwali ye-nickel iindidi ezimbini. Ukusetyenziswa okuqhelekileyo: izixhobo ze-pulp kunye nephepha Umtshintshi wobushushu, izixhobo zoomatshini, izixhobo zokudaya, izixhobo zokuhlamba iifilimu, imibhobho, izinto zokwakha zangaphandle zommandla wonxweme, njl.
Umphezulu wepleyiti yentsimbi engagqwaliyo uthambile, uqinile kwaye unamandla oomatshini, kwaye uyamelana ne-asidi, igesi ye-alkaline, isisombululo kunye nokunye ukugqwala kwemidiya. Yintsimbi ye-alloy ekulula ukuyigqwala, kodwa ayinayo igqwala ngokupheleleyo.
