Nasckel chromium-ka alfoy Resistohm 40 caabbinta caabbinta caabbinta roo40c20 silig korantada
Ni40cr20waa austenitic chromium alfoy (nicr alloey) si loogu isticmaalo heerkulka illaa 1100 ° C (2010 ° F). Alloy-ga waxaa lagu gartaa iska caabbinta sare iyo iska caabin wanaagsan oo ixtiraadsan. Waxay leedahay qafis fiican ka dib isticmaalka iyo adeegsiga wanaagsan.
Codsiyada caadiga ah ee NI40cr20 waa kuleyliyeyaal habeen-habeen ah, kuleyliyeyaasha shisheeyaha, kululeeyaha culus iyo kuleyliyaha taageerayaasha. Alloy-ka waxaa sidoo kale loo isticmaalaa kuleylka kuleylka iyo kuleylka xargaha ee ku dhaca iyo walxaha qulqulka, bustayaasha korantada, burooyinka korantada iyo gogosha, kuleylka gawaarida, kuleylka dabaqa iyo kuleylka dabaqa, iska caabinnada dabaqa.
