Ohun elo
Alloy 825 jẹ austenitic nickel-iron-chromium alloy tun ṣe alaye nipasẹ awọn afikun ti molybdenum, bàbà ati titanium. O ti ni idagbasoke lati pese atako alailẹgbẹ si ọpọlọpọ awọn agbegbe ibajẹ, mejeeji oxidizing ati idinku.
Alloy 825 jẹ idagbasoke lati pese atako alailẹgbẹ si ọpọlọpọ awọn agbegbe ibajẹ, mejeeji oxidizing ati idinku. Pẹlu iwọn akoonu nickel kan laarin 38% –46%, ipele yii ṣe afihan resistance ti o sọ si didin ipata wahala (SCC) ti o fa nipasẹ awọn kiloraidi ati alkalis. Akoonu nickel to fun atako chloride-ion wahala-ibajẹ wo inu. Nickel, ni apapo pẹlu molybdenum ati bàbà, tun funni ni atako ti o tayọ si idinku awọn agbegbe bii awọn ti o ni imi-ọjọ ati awọn acids phosphoric ninu.
Awọn chromium ati akoonu molybdenum tun pese resistance pitting to dara ni gbogbo awọn agbegbe ayafi awọn solusan chloride oxidizing lagbara. Ti a lo bi ohun elo ti o munadoko ni ọpọlọpọ awọn agbegbe ilana, alloy 825 n ṣetọju awọn ohun-ini ẹrọ ti o dara lati awọn iwọn otutu cryogenic titi di 1,000 ° F.
Afikun ti titanium ṣe iduroṣinṣin Alloy 825 lodi si ifamọ ni ipo isọpọ ti n jẹ ki alloy sooro si ikọlu intergranular lẹhin ifihan si awọn iwọn otutu ni sakani ti yoo ṣe akiyesi awọn irin alagbara ti ko ni iduroṣinṣin. Awọn iṣelọpọ ti Alloy 825 jẹ aṣoju ti nickel-base alloys, pẹlu ohun elo ti o wa ni imurasilẹ ati ki o weldable nipasẹ awọn ọna ẹrọ pupọ.
Awọn ohun elo yi ni o ni o tayọ formability, aṣoju ti nickel-mimọ alloys, gbigba awọn ohun elo lati wa ni ti tẹ si lalailopinpin kekere radii. Annealing lẹhin atunse ko ṣe pataki ni deede.
O jẹ iru si alloy 800 ṣugbọn o ni ilọsiwaju si resistance si ipata olomi. O ni atako ti o dara julọ si idinku mejeeji ati awọn acids oxidizing, si idamu-ipata wo inu, ati si ikọlu agbegbe gẹgẹbi pitting ati ipata crevice. Alloy 825 jẹ paapaa sooro si imi-ọjọ ati awọn acids phosphoric. Yi nickel irin alloy ti wa ni lilo fun kemikali processing, idoti-Iṣakoso-ẹrọ, epo ati gaasi fifi ọpa daradara, iparun idana atunṣeto, acid gbóògì, ati pickling ẹrọ.
