Ulwahlulo lwensimbi engenasici

Kukho iindidi ezintlanu ezisisisekoyenziwe ngentsimbi eshayinayo:i-austenitic, i-ferritic, i-martensitic, i-duplex, kunye nokuqina kwemvula.

(1) Iintsimbi ze-Austenitic ezingenasici azikho magnetic, kwaye amabakala ensimbi amele i-18% ye-chromium eyongeziweyo kunye nenani elithile le-nickel elongezelelweyo ukwandisa ukuxhathisa ukubola.Zisetyenziswa ngokubanzi amabakala entsimbi.

(2) I-Ferrite inozibuthe, kunye nechromium isiqulatho sayo esiphambili, kunye nomlinganiselo we-17%.Esi sixhobo sinokuxhathisa okulungileyo kwe-oxidation.

(3) I-Martensitic steel stainless nayo imagnetic, umxholo we-chromium udla ngokuba yi-13%, kwaye iqulethe umlinganiselo ofanelekileyo wekhabhoni, onokuthi uqiniswe ngokucinywa kunye nokuvutha.

(4) I-Duplex yensimbi engenasici inesakhiwo esixubileyo se-ferrite kunye ne-austenite, umxholo we-chromium uphakathi kwe-18% kunye ne-28%, kwaye umxholo we-nickel uphakathi kwe-4.5% kunye ne-8%.Zixhathisa kakhulu kwi-corrosion ye-chloride.Iziphumo ezilungileyo.

(5)Umxholo oqhelekileyo we-chromium kwi-precipitation yensimbi engenasici yi-17, kwaye inani elithile le-nickel, ithusi kunye ne-niobium yongezwa, enokuthi iqiniswe yimvula kunye nokuguga.

Ngokwesakhiwo se-metallographic, inokwahlulwa ibe:

(1)Insimbi engenasici ye-Ferritic (i-400 series), i-chromium insimbi engenasici, imelwe ikakhulu yi-Gr13, G17, Gr27-30;

(2)I-Austenitic insimbi engenasici (i-300 series), i-chromium-nickel insimbi engenasici, imelwe ngokukodwa ngu-304, 316, 321, njl.;

(3)Intsimbi ye-Martensitic (i-series ye-200), i-chromium-manganese insimbi engenasici, i-carbon content, ikakhulukazi imelwe yi-1Gr13, njl.
