Iingenelo eziphambili ze-Incoloy 825

Ukumelana ne-Acid ephezulu– I-Incoloy 825 inika ukumelana okugqwesileyo ne-sulfuric, phosphoric, kunye ne-nitric acids kuluhlu olubanzi loxinzelelo kunye nobushushu. Ukudibana kwe-nickel, i-chromium, i-molybdenum, kunye ne-copper kudala izinto ezimelana nokunciphisa kunye nokuxovula iindawo ze-asidi. Kwi-sulfuric acid ukuya kuthi ga kwi-40% yoxinzelelo kwi-100°C, izinga lokugqwala lingaphantsi kwe-0.5 mm ngonyaka.

Ukumelana nokugqwala kwePitting kunye neCrivice– Umxholo we-molybdenum (2.5-3.5%) unika ukumelana okuhle kakhulu nokugqwala kwemingxuma kwiindawo ezine-chloride. Ixabiso le-PREN elimalunga nama-36 liqinisekisa ukusebenza okuthembekileyo kwimithombo yamanzi olwandle kunye ne-chloride-rich process apho intsimbi engagqwaliyo ye-316L iya kusilela khona.

Ukumelana nokuqhekeka koxinzelelo– Umxholo ophezulu we-nickel (38-46%) unika ukumelana okugqwesileyo nokuqhekeka koxinzelelo olubangelwa yi-chloride. I-Incoloy 825 ayichaphazeleki yi-SCC emanzini olwandle, ityuwa, kunye neendawo ezine-chloride apho iintsimbi ezingenanto ezingama-304/316 zihlala zingasebenzi.

Uzinzo lweTitanium– Ukongezwa kwe-titanium (0.6-1.2%) kuzinzisa i-alloy kwi-corrosion ephakathi kweegranular. Ngokwenza i-TiC ezinzileyo kunye ne-TiN precipitates, i-titanium ithintela ukwakheka kwe-chromium carbides kwimida yeenkozo ngexesha lokudityaniswa, ukuqinisekisa ukumelana nokugqwala kwindawo echaphazelekileyo bubushushu.

Ukudityaniswa kakuhle– I-Incoloy 825 ingadityaniswa kusetyenziswa i-TIG, i-MIG, i-resistance welding, kunye nezinye iinkqubo ezisemgangathweni. I-matching filler metal ERNiFeCr-1 (AWS A5.14) iyacetyiswa kwizicelo ezifuna ikhemistri efanayo. Akukho kufudumeza kwangaphambili okufunekayo ngokubanzi, kwaye unyango lobushushu emva kokudityaniswa alufuneki kwizicelo ezininzi.

Iipropati Ezilungileyo Zoomatshini– I-alloy igcina iipropati ezilungileyo zoomatshini ukusuka kumaqondo obushushu aphantsi ukuya kuthi ga kwi--184°C ukuya kuthi ga kwi-538°C (1000°F). Ukusebenza ngokubanda kwandisa kakhulu amandla (ukuya kuthi ga kwi-1,035 MPa tensile) ngelixa kugcinwa ukugudiseka okwaneleyo.

Ukuthobela i-NACE MR0175 / ISO 15156– I-Incoloy 825 ifanelekile kwizicelo zenkonzo emuncu kwishishini leoyile negesi, imelana nokuqhekeka koxinzelelo lwe-sulfide (SSC) kunye nokuqhekeka okubangelwa yi-hydrogen (HIC) kwiindawo ezine-H₂S.
