INCOLOY 825 (UNS N08825 / NS142)
Codsiga
Alloy 825 waa isku-darka nikkel-bir-chromium oo austenitic ah oo sidoo kale lagu qeexay ku darista molybdenum, naxaas iyo titanium. Waxaa loo sameeyay si ay u bixiso iska caabin aad u weyn oo ku wajahan deegaanno badan oo daxal leh, labadaba oksaydheynta iyo yaraynta.
Alloy 825 waxaa loo sameeyay si ay u bixiso iska caabin heer sare ah oo ka dhan ah deegaanno badan oo daxal leh, labadaba oksaydheynta iyo yaraynta. Iyada oo heerka nikkel uu u dhexeeyo 38%-46%, heerkani wuxuu muujinayaa iska caabin cad oo ka dhan ah dillaaca daxalka cadaadiska (SCC) oo ay sababaan chlorides iyo alkalis. Tirada nikkel-ku waxay ku filan tahay iska caabinta dillaaca walbahaarka-daxalka chloride-ion. Nikkel-ku, oo ay weheliso molybdenum iyo naxaas, wuxuu sidoo kale bixiyaa iska caabin heer sare ah oo ka dhan ah deegaannada yareeya sida kuwa ka kooban asiidhyada sulfuric iyo fosfoorik.
Waxyaabaha ku jira chromium iyo molybdenum waxay sidoo kale bixiyaan iska caabin wanaagsan oo ku saabsan biqilka dhammaan deegaannada marka laga reebo xalalka chloride-ka ee si xooggan u oksaydha. Iyada oo loo isticmaalo sidii walax wax ku ool ah oo ku jirta noocyo kala duwan oo jawi-hawleed ah, daawaha 825 wuxuu ilaaliyaa sifooyin farsamo oo wanaagsan laga bilaabo heerkulka cryogenic ilaa 1,000° F.
Ku darista titanium-ku waxay xasilisaa Alloy 825 ka hortagga dareenka xaaladda alxanka taasoo ka dhigaysa alxanka mid u adkaysta weerarka isku-dhafka ah ka dib marka uu la kulmo heerkul ku jira meel u dhow kaas oo dareensiin kara biraha aan xasilloonayn ee aan xasilloonayn. Samaynta Alloy 825 waa mid caadi ah oo ka samaysan alxanka nikkel-ka, iyadoo walaxdu ay si fudud u samaysan karto oo ay ku shaqeyn karto farsamooyin kala duwan.
Maaddadani waxay leedahay qaab-dhismeed aad u fiican, oo caadi u ah alwaaxyada salka ku haya nikkel, taasoo u oggolaanaysa walxaha in loo laabo raajada aad u yar. Qaboojinta ka dib foorarsiga badanaa looma baahna.
Waxay la mid tahay dahaarka 800 laakiin waxay hagaajisay iska caabinta daxalka biyaha. Waxay leedahay iska caabin aad u fiican oo ku wajahan asiidhyada yareeya iyo kuwa oksaydhka sameeya, dillaaca cadaadiska-daxalka, iyo weerarka maxalliga ah sida daxalka godka iyo daloolka. Dahaarka 825 wuxuu si gaar ah u adkaystaa asiidhyada sulfuric iyo fosfoorik. Dahaarkan birta nikkel waxaa loo isticmaalaa farsamaynta kiimikada, qalabka xakamaynta wasakhowga, tuubooyinka ceelasha saliidda iyo gaaska, dib-u-habaynta shidaalka nukliyeerka, soo saarista asiidhka, iyo qalabka lagu shubo.
