S32760 Mea Pono
S32760 (F55), X2CrNiMoCuWN 25.7.4, German standard 1.4501, ikaika ikaika a me ka corrosion resistance, hoʻohana nui ʻia i ka hana kemika, petrochemical a me nā lako subsea.Loaʻa iā ia ke kūpaʻa ikaika i ka chloride corrosion, kiʻekiʻe thermal conductivity a me ka haʻahaʻa haʻahaʻa hoʻonui hoʻonui.ʻOi aku ka kiʻekiʻe o ka chromium, molybdenum a me ka nitrogen maʻiʻo, he kiʻekiʻe kona kūʻē ʻana i ka pitting, crevice corrosion a me ka corrosion maʻamau.
ʻO Alloy S32760 kahi kila kila kila super duplex i hoʻolako ʻia i ka hana wela a me ke kūlana annealed solution.Ma ke ʻano he kila stainless super duplex, hoʻohui ia i nā ʻano makemake o nā austenitic a me nā kila ferritic.Loaʻa ka ʻike kiʻekiʻe o ka chromium, molybdenum a me ka nitrogen i kahi Pitting Resistance Equivalent Number (PREN) > 40, e hāʻawi ana i nā mana ʻoi aku ka maikaʻi o ka lua a me ka puʻupuʻu ma mua o nā kila kuhili ʻole austenitic a me ka duplex ma kahi kokoke i nā mea hoʻoheheʻe a pau, a me kahi wela pitting koʻikoʻi E akahele ma luna o 50°C.Aia pū kekahi mana o ka formula PREN me W ma ke ʻano he hopena maikaʻi i ke kūʻē ʻana o ka lua.
