INCOOY 825 (UNS N08825 / NS142)
Ngwa
Alloy 825 bụ ihe austenitic nickel-iron-chromium alloy kọwakwara site na mgbakwunye nke molybdenum, ọla kọpa na titanium. Emepụtara ya iji nye nguzogide pụrụiche nye ọtụtụ ebe na-emebi emebi, ma oxidizing na ibelata.
Emepụtara Alloy 825 iji nye nguzogide pụrụ iche nye ọtụtụ gburugburu ebe obibi na-emebi emebi, ma oxidizing na ibelata. Site na ọdịnaya nickel dị n'etiti 38%-46%, ọkwa a na-egosipụta nguzogide nrụrụaka corrosion cracking (SCC) nke chlorides na alkalis na-ebute. Ọdịnaya nickel zuru oke maka iguzogide nrụgide-corrosion chloride-ion. Nickel, yana njikọ nke molybdenum na ọla kọpa, na-enyekwa nnukwu nguzogide ibelata gburugburu ebe obibi dịka ndị nwere sulfuric na phosphoric acid.
Ọdịnaya chromium na molybdenum na-enyekwa ezigbo nkwụsi ike na gburugburu ebe niile ma ewezuga ngwọta chloride na-ekpo ọkụ. Ejiri ya mee ihe dị ka ihe dị irè na gburugburu usoro nhazi dịgasị iche iche, alloy 825 na-ejigide ihe ndị dị mma site na okpomọkụ cryogenic ruo 1,000 ° F.
Mgbakwunye titanium na-eme ka Alloy 825 kwụsie ike megide mmetụta uche na ọnọdụ welded na-eme ka alloy na-eguzogide ọgụ nke intergranular mgbe ekpughere ya na okpomọkụ n'ụdị nke ga-eme ka igwe anaghị agba nchara na-enweghị isi. Nmepụta nke Alloy 825 bụ ihe atụ nke nickel-base alloys, na ihe onwunwe na-adị ngwa ngwa na weldable site n'ụdị dị iche iche.
Nke a ihe onwunwe nwere magburu onwe formability, ụdị nke nickel-base alloys, ikwe ka ihe na-ehulata ka ukwuu obere radii. Ịkwụsị mgbe ehulata adịghị mkpa.
Ọ dị ka alloy 800 mana ọ kwalitela nguzogide corrosion aqueous. Ọ nwere ezigbo nguzogide ma ibelata ma oxidizing acids, na mgbawa nrụgide-corrosion, yana ọgụ nke mpaghara dị ka pitting na crevice corrosion. Alloy 825 na-eguzogide ọgwụ sulfuric na phosphoric acid karịsịa. A na-eji nickel ígwè alloy a maka nhazi kemịkalụ, akụrụngwa na-emetọ mmetọ, ọkpọkọ mmanụ na gas, nrụpụta mmanụ nuklia, mmepụta acid, na akụrụngwa pickling.
