Hastelloy C-4
Inkcazelo emfutshane:
I-Hastelloy C-4 (UNS NO6455)
Iimpawu zeHastelloy C-4 kunye neSishwankathelo seSicelo:
I-alloy yi-austenitic low-carbon nickel-molybdenum-chromium alloy. Umahluko ophambili phakathi kwe-Nicrofer 6616 hMo kunye nezinye ii-alloys zemichiza efanayo ephuhliswe ngaphambili yikhabhoni ephantsi, i-silicon, isinyithi kunye ne-tungsten. Olu qulunqo lweekhemikhali lubonelela ngozinzo olugqwesileyo kwi-650-1040 ° C kunye nokuphucula ukuxhathisa kwi-corrosion intergranular, ukuphepha ukuxhatshazwa kwe-edge line kunye ne-weld HAZ corrosion phantsi kweemeko ezifanelekileyo zokuvelisa. I-alloy esetyenziswe kwiinkqubo ze-flue gas desulfurization, i-pickling kunye ne-acid regeneration plant, i-acetic acid kunye nokuveliswa kweekhemikhali zezolimo, ukuveliswa kwe-titanium dioxide (indlela ye-chloride), i-electrolytic plating.

Inkqubo yokusebenza kweHastelloy C-4 kunye neemfuno:
I-1, kwinkqubo yonyango lobushushu ayikwazi ukudibana nesalfure, i-phosphorus, ilothe kunye nezinye iindawo eziphantsi zokunyibilika kwesinyithi, okanye i-alloy iya kuba yi-brittle, kufuneka ithathele ingqalelo ukususa njengepeyinti yokumakisha, ipeyinti yesalathisi sobushushu, iikhrayoni ezinemibala, izithambiso, amafutha. kunye nokunye ukungcola. Umgangatho wesulfure we-fuel uphantsi ungcono, umxholo wesulfure wegesi yendalo kufuneka ube ngaphantsi kwe-0.1%, umxholo wesulfure weoli enzima kufuneka ube ngaphantsi kwe-0.5%. Ukufudumala kwesithando sombane kukhetho olungcono, kuba isithando sombane sinokulawula ngokuchanekileyo ubushushu kunye negesi yomlilo ihlambulukile. Ukuba igesi yesitovu segesi icocekile ngokwaneleyo, ungakhetha.
2, i-alloy processing thermal iqondo lobushushu boluhlu lwe-1080 ℃ ~ 900 ℃, indlela yokupholisa yokupholisa kwamanzi okanye okunye ukupholisa ngokukhawuleza. Ukuqinisekisa ukuxhathisa kwe-corrosion, unyango lobushushu kufuneka lwenziwe emva kokulungiswa kobushushu besisombululo.
