INCOLOY 825 (UNS N08825 / NS142)
Ngwa
Alloy 825 bụ ihe austenitic nickel-iron-chromium alloy nke a na-akọwakwa site na mgbakwunye nke molybdenum, ọla kọpa na titanium. E mepụtara ya iji nye ike iguzogide ọtụtụ gburugburu ebe obibi na-emebi ihe, ma na-eme ka ọ dị ọcha ma na-ebelata.
E mepụtara Alloy 825 iji nye ike iguzogide ọtụtụ gburugburu ebe obibi na-emebi ihe, ma nke na-eme ka ọ dị ọcha ma nke na-ebelata. Site na ọdịnaya nickel dị n'etiti 38%–46%, ọkwa a na-egosipụta ike iguzogide mgbawa corrosion (SCC) nke chlorides na alkalis kpatara. Ọdịnaya nickel zuru oke maka iguzogide mgbawa nrụgide chloride-ion-corrosion. Nickel, yana molybdenum na ọla kọpa, na-enyekwa ike iguzogide gburugburu ebe obibi dị ka ndị nwere sulfuric na phosphoric acid.
Ọdịnaya chromium na molybdenum na-enyekwa ezigbo iguzogide ọkpọkọ n'ebe niile ma e wezụga ngwọta chloride siri ike. Ejiri ya dị ka ihe dị irè n'ọtụtụ ebe usoro, alloy 825 na-ejigide ezigbo ihe onwunwe igwe site na okpomọkụ cryogenic ruo 1,000° F.
Mgbakwunye nke titanium na-eme ka Alloy 825 kwụsie ike megide mmetụta uche n'ọnọdụ as-welded na-eme ka alloy ahụ ghara iguzogide mwakpo intergranular mgbe ekpughere ya na okpomọkụ n'ọtụtụ ebe nke ga-eme ka ígwè anaghị agba nchara na-adịghị akwụsi ike. Mmepụta nke Alloy 825 bụ ihe a na-ahụkarị na alloys-base nickel, yana ihe dị iche iche nwere ike ịkpụzi ma sie ike ịgbado ọkụ site na usoro dị iche iche.
Ihe a nwere ọdịdị dị mma, nke a na-ahụkarị na alloys nke nickel, nke na-eme ka ihe ahụ gbagọọ ruo obere radii. Ọ dịghị mkpa ka a na-emechi ya mgbe a gbagọrọ agbagọ.
O yiri alloy 800 mana o nwere ezigbo iguzogide corrosion mmiri. O nwere ezigbo iguzogide ma mbelata na oxidizing acid, na mgbawa nrụgide-corrosion, na mwakpo mpaghara dịka pitting na crevice corrosion. Alloy 825 na-eguzogide karịsịa sulfuric na phosphoric acid. A na-eji alloy ígwè nickel a eme ihe maka nhazi kemịkalụ, akụrụngwa njikwa mmetọ, ọkpọkọ mmanụ na gas, nhazi mmanụ nuklia, mmepụta acid, na ngwa ịtụtụ ihe.
