I-Stainless Steel Round Bar enoMgangatho Olungileyo

Intsimbi (Fe): yinto esisiseko yentsimbi yentsimbi;

I-Chromium (Cr): yeyona nto iphambili yokwenza i-ferrite, i-chromium idityaniswe neoksijini inokuvelisa ifilimu enganyangekiyo ye-Cr2O3, yenye yezinto ezisisiseko zentsimbi engatyiwayo ukugcina ukuxhathisa kokubola, umxholo wechromium wongeza isakhono sokulungisa ifilimu yentsimbi, intsimbi egqwesileyo yentsimbi engaphezulu kwe-1% kufuneka ibe ngaphezulu komxholo we-chromium.

I-Carbon (C): yinto eyomeleleyo yokwenza i-austenite, inokuphucula kakhulu amandla ensimbi, ngaphezu kwekhabhoni kwi-corrosion resistance nayo inefuthe elibi;

I-Nickel (Ni): yinto ephambili yokwenza i-austenite, inokunciphisa ukubola kwentsimbi kunye nokukhula kweenkozo ngexesha lokufudumala;

I-Molybdenum (Mo): i-carbide forming element, i-carbide eyenziwe izinzile ngokugqithisileyo, inokuthintela ukukhula kwengqolowa ye-austenite xa ishushu, ukunciphisa i-superheat sensitivity yensimbi, ngaphezu koko, i-molybdenum inokwenza ifilimu ye-passivation ibe yinkimbinkimbi kwaye iqinile, ngaloo ndlela iphucula ngempumelelo i-stainless steel Cl- corrosion resistance;

I-Niobium, i-titanium (i-Nb, i-Ti): i-carbide enamandla yokwenza izinto, inokuphucula ukuxhathisa kwentsimbi kwi-corrosion intergranular. Nangona kunjalo, i-titanium carbide inefuthe elibi kumgangatho ophezulu wensimbi engenasici, ngoko ke insimbi engenasici eneemfuno eziphezulu zomgangatho jikelele iphuculwe ngokungeza i-niobium ukuphucula ukusebenza.

I-Nitrogen (N): yinto eyomeleleyo yokwenza i-austenite, inokuphucula kakhulu amandla entsimbi. Kodwa ukuguga kokuqhekeka kwensimbi engenasici kunempembelelo enkulu, ngoko ke intsimbi engenasici kwiinjongo zokunyathela ukulawula ngokungqongqo umxholo wenitrogen.

I-Phosphorus, isulfure (P, S): yinto enobungozi kwinsimbi engenasici, ukuxhatshazwa kwe-corrosion kunye ne-stamping yensimbi engenasici kunokuba nefuthe elibi.
