Hastelloy C-4
Tsanangudzo Pfupi
Hastelloy C-4 (UNS NO6455)
Hastelloy C-4 Zvimiro uye Mashandisirwo Muchidimbu:
Iyo alloy ndeye austenitic yakaderera-kabhoni nickel-molybdenum-chromium alloy. Musiyano mukuru pakati peNicrofer 6616 hMo uye mamwe maalloys emakemikari akafanana akagadzirwa kare akaderera kabhoni, silicon, iron uye tungsten. Ichi chemikemikari inoumba inopa kugadzikana kwakanakisa pa650-1040 ° C uye yakagadziridzwa kuramba kune intergranular corrosion, kudzivirira kumucheto mutsetse ngura susceptibility uye weld HAZ ngura pasi pemamiriro ekugadzira akakodzera. Alloy inoshandiswa muflue gasi desulfurization masisitimu, pickling uye asidi yekuvandudza chirimwa, acetic acid uye kugadzirwa kwemakemikari ekurima, titanium dioxide kugadzirwa (chloride nzira), electrolytic plating.

Hastelloy C-4 maitiro ekuita uye zvinodiwa:
1, Mukupisa kurapwa haigone kusangana nesarufa, phosphorus, lead uye imwe yakaderera simbi inonyungudika, kana alloy ichava brittle, inofanirwa kuterera kubvisa senge yekumaka pendi, tembiricha chiratidzo pendi, makrayoni ane mavara, mafuta ekuzora. nedzimwe tsvina. Iyo yakaderera iyo sulfur yemukati yemafuta zviri nani, iyo sulfur yemukati yegasi yegasi inofanira kunge iri pasi pe0.1%, iyo sulfur yemukati yemafuta anorema inofanira kunge isingasviki 0.5%. Kupisa kwechoto chemagetsi isarudzo iri nani, nekuti choto chemagetsi chinogona kunyatso kudzora tembiricha uye gasi rechoto rakachena. Kana iyo gasi chitofu gasi yakachena zvakakwana, unogona kusarudza.
2, alloy thermal processing tembiricha ye1080 ℃ ~ 900 ℃, nzira yekutonhora yekutonhora kwemvura kana kumwe kutonhora nekukurumidza. Kuti ive nechokwadi chekudzivirira kwakanakisisa kwekuora, kurapwa kwekupisa kunofanira kuitwa mushure mekugadzirisa kupisa kwekugadzirisa.
