I-ALLOY B-2, i-UNS N10665

I-ALLOY B-2, i-UNS N10665

Ingxubevange B-2 UNS N10665
Isishwankathelo Ingxubevange ye-nickel-molybdenum enganyangekiyo ekutyeni, ingxubevange ye-Alloy B-2 ibonisa ukuxhathisa okugqwesileyo kokutya kwimithombo yeendaba ethobayo efana ne-hydrochloric acid kuluhlu olubanzi lwamaqondo obushushu kunye noxinzelelo, kunye nakwi-asidi yesulfuric exineneyo nangona inekloridi encinci. ungcoliso. Inokusetyenziswa kwakhona kwi-acetic kunye ne-phosphoric acids, kunye noluhlu olubanzi lwee-asidi eziphilayo. I-alloy inokumelana kakuhle ne-chloride-induced stress corrosion cracking (SCC).

Microstructure I-alloy B-2 inobuso-centered-cubic structure. Ikhemikhali elawulwa yialloy enobuncinci bentsimbi kunye nomxholo wechromium inciphisa umngcipheko wokwenzeka kwe-embrittlement ngexesha lokwenziwa, njengoko oku kubambezela imvula yesigaba se-Ni4Mo kwiqondo lobushushu le-700-800 ℃.
Abalinganiswa 1. I-chemistry elawulwayo kunye nentsimbi encinci kunye nomxholo we-chrlmium ukubuyisela ukubunjwa kwe-oda ye-β-phase Ni4Mo;
2. Ukuxhathisa okubonakalayo kwi-corrosion kwindawo yokunciphisa;
3. Ukuchasana okugqwesileyo kwi-acid-concentrated sulfuric acid kunye nenani le-non-oxidizing acids;
4. Ukuchasana okulungileyo kwi-chloride-induced stress-corrosion cracking (SCC);
5. Ukuchasana okulungileyo kuluhlu olubanzi lwee-acids eziphilayo.
Ukunyangwa kokuMhlwa Ikhabhoni ephantsi kakhulu kunye nomxholo we-silicon ye-Hastelloy B-2 inciphisa imvula ye-carbides kunye nezinye izigaba kwindawo echaphazelekayo yokushisa ye-welds kwaye iqinisekisa ukuxhathisa ukubola okwaneleyo nakwimeko edibeneyo. I-Hastelloy B-2 ibonisa ukuxhathisa okugqwesileyo kwi-corrosion kwimidiya yokunciphisa ngokukrakra njenge-hydrochloric acid kuluhlu olubanzi lwamaqondo obushushu kunye noxinzelelo, kunye ne-medium-concentrated sulfuric acid nangona ungcoliseko oluncinci lwe-chloride. Inokusetyenziswa kwakhona kwi-acetic kunye ne-phosphoric acids. I-Optimum resistance corrosion resistance ingafumaneka kuphela ukuba izinto eziphathekayo zikwimeko echanekileyo ye-metallurgical kwaye ibonisa isakhiwo esicocekileyo.
Usetyenziso I-alloy B-2 isetyenziselwa uluhlu olubanzi lwezicelo kwishishini lenkqubo yeekhemikhali, ngokukodwa kwiinkqubo ezibandakanya i-sulphuric, i-hydrochloric, i-phosphoric kunye ne-acetic acid. I-B-2 ayikhuthazwa ukuba isetyenziswe xa kukho ityuwa ye-ferric okanye i-cupric salts njengoko ezi tyuwa zinokubangela ukusilela kokutya ngokukhawuleza. Iityuwa ze-ferric okanye i-cupric zingakhula xa i-hydrochloric acid idibana nentsimbi okanye ubhedu.
