Hastelloy C-4

Nā hiʻohiʻona a me nā noi o Hastelloy C-4:
ʻO ka huila he austenitic low-carbon nickel-molybdenum-chromium alloy. ʻO ka ʻokoʻa nui ma waena o Nicrofer 6616 hMo a me nā ʻāpana ʻē aʻe o ka haku melemele like i hoʻomohala ʻia ma mua he kalapona haʻahaʻa, silika, hao a me tungsten. Hāʻawi kēia hui kemika i ke kūpaʻa maikaʻi loa ma 650-1040 ° C a hoʻomaikaʻi i ke kūpaʻa ʻana i ka corrosion intergranular, ka pale ʻana i ka hiki ʻole o ka corrosion o ka laina kihi a weld HAZ corrosion ma lalo o nā kūlana hana kūpono. Hoʻohana ʻia ʻo Alloy i nā ʻōnaehana desulfurization flue gas, pickling a me ka mea kanu hoʻoulu hou ʻana i ka waikawa, ka acetic acid a me ka hana ʻana i nā kemika mahiʻai, titanium dioxide production (chloride method), electrolytic plating.
ʻO Hastelloy C-4 mau makamae like:
NS335 (Kina) W.Nr.2.4610 NiMo16Cr16Ti (Kelemānia)

Nā kūlana hana o Hastelloy C-4:

Hana a me nā koi o ke kaʻina hana Hastelloy C-4:

1, I ka wela lapaʻau kaʻina hana hiki ole ke hoʻokaʻaʻike me ka sulfur, phosphorus, ke alakaʻi a me nā haʻahaʻa heheʻe helu wahi metala, ai ole ia, e lilo ka mea hao e brittle, pono e hoʻolohe i ka wehe 'ana e like me ka makaʻana pena, mahana hōʻailona pena, kala kala, lubricants, wahie. a me nā lepo ʻē aʻe. ʻO ka haʻahaʻa o ka sulfur maʻiʻo o ka wahie ʻoi aku ka maikaʻi, ʻoi aku ka liʻiliʻi o ka sulfur maʻiʻo o ke kinoea maoli ma mua o 0.1%, ʻoi aku ka liʻiliʻi o ka ʻaila sulfur ma lalo o 0.5%. ʻOi aku ka maikaʻi o ka hoʻomehana ʻana i ka umu uila, no ka mea, hiki i ka umu uila ke hoʻomalu pono i ka mahana a maʻemaʻe ke kinoea umu. Inā lawa ka maʻemaʻe o ka umu ahi, hiki iā ʻoe ke koho.
2, ka pae wela wela o ka 1080 ℃ ~ 900 ℃, ke ʻano hoʻoluʻu no ka hoʻoluʻu wai a i ʻole ka hoʻoluʻu wikiwiki. No ka hōʻoia ʻana i ka pale corrosion maikaʻi loa, pono e hoʻokō ʻia ka mālama wela ma hope o ka mālama ʻana i ka wela.
