S32760 Khoom Khoom
S32760 (F55), X2CrNiMoCuWN 25.7.4, German tus qauv 1.4501, muaj zog lub zog thiab corrosion kuj, feem ntau yog siv rau hauv kev ua tshuaj, petrochemical thiab subsea khoom.Nws muaj zog tiv thaiv chloride corrosion, siab thermal conductivity thiab qis thermal expansion coefficient.Ntau dua chromium, molybdenum thiab nitrogen cov ntsiab lus, nws muaj kev ua haujlwm siab rau pitting, crevice corrosion thiab dav corrosion.
Alloy S32760 yog ib qho super duplex stainless hlau nkag rau hauv qhov kub ua haujlwm thiab kev daws teeb meem annealed.Raws li ib tug super duplex stainless hlau, nws combines lub ntshaw yam ntawm austenitic thiab ferritic steels.Siab chromium, molybdenum thiab nitrogen cov ntsiab lus ua rau Pitting Resistance Equivalent Number (PREN) > 40, muab superior pitting thiab crevice corrosion muaj peev xwm tshaj austenitic thiab duplex stainless hlau nyob rau hauv yuav luag tag nrho cov corrosive media, thiab ib tug tseem ceeb pitting kub Ceev faj tshaj 50 ° C.Ib qho qauv ntawm PREN formula kuj suav nrog W raws li qhov txiaj ntsig zoo rau tag nrho pitting kuj.
Nws muaj lub zog ntau dua li austenitic thiab 22% Cr duplex stainless hlau thiab tau teev rau NACE MR 0175 rau kev pabcuam qaub thiab ASME rau kev siv lub nkoj siab.
