S32760 Meatotino Meatotino
S32760 (F55), X2CrNiMoCuWN 25.7.4, tulaga Siamani 1.4501, malosi malosi ma le corrosion teteʻe, e masani ona faʻaaogaina i vailaʻau faʻasolosolo, petrochemical ma mea i lalo o le sami.E malosi le tete'e i le chloride corrosion, conductivity vevela maualuga ma maualalo le fa'alauteleina o le vevela coefficient.O le maualuga o le chromium, molybdenum ma le nitrogen, e maualuga lona teteʻe i pitting, crevice corrosion ma lautele corrosion.
Alloy S32760 o se super duplex u'amea u'amea tu'uina atu i le vevela galue ma fofo tulaga annealed.I le avea ai o se uamea sili ona leaga, e tuʻufaʻatasia vaega manaʻomia o austenitic ma ferritic steels.Ole maualuga ole chromium, molybdenum ma le nitrogen e maua ai le Pitting Resistance Equivalent Numera (PREN) > 40, e maua ai le sili atu o le gaogao ma le u'amea malosi i luga o austenitic ma duplex u'amea u'amea i le toetoe o ala pala uma, ma se vevela mata'utia Fa'aeteete i luga ole 50°C.O se fa'asologa o le fua ole PREN e aofia ai fo'i le W ose a'afiaga lelei ile fa'ato'a fa'ato'aga.
E ofoina atu le malosi sili atu nai lo austenitic ma 22% Cr duplex uamea u'amea ma o lo'o lisiina ile NACE MR 0175 mo le 'au'aunaga oona ma le ASME mo fa'aoga va'a mamafa.
