ʻO Hastelloy C-4

Nā Hiʻohiʻona a me nā Hana o Hastelloy C-4:
He mea hoʻohuihui austenitic low-carbon nickel-molybdenum-chromium ka mea hoʻohuihui. ʻO ka ʻokoʻa nui ma waena o Nicrofer 6616 hMo a me nā mea hoʻohuihui ʻē aʻe o ke ʻano kemika like i hoʻomohala ʻia ma mua, ʻo ia ke kalapona haʻahaʻa, silicon, hao a me ka tungsten. Hāʻawi kēia ʻano kemika i ke kūpaʻa maikaʻi loa ma 650-1040 ° C a hoʻomaikaʻi i ke kūʻē ʻana i ka corrosion intergranular, e pale ana i ka hiki ke hoʻopilikia i ka laina lihi a me ka weld HAZ corrosion ma lalo o nā kūlana hana kūpono. Hoʻohana ʻia ka mea hoʻohuihui i nā ʻōnaehana desulfurization gas flue, ka pickling a me ka hana hou ʻana o ka waikawa, ka hana ʻana o ka waikawa acetic a me nā kemika mahiʻai, ka hana ʻana o ka titanium dioxide (ʻano chloride), ka electrolytic plating.
ʻO Hastelloy C-4 Nā lama like:
NS335 (Kina) W.Nr.2.4610 NiMo16Cr16Ti (Kelemānia)
ʻO Hastelloy C-4 ka hoʻohuihui kemika:

Nā Waiwai Kino o Hastelloy C-4:

Nā Waiwai Mekanika Hastelloy C-4: (nā waiwai mīkini liʻiliʻi loa ma 20 ℃):

Nā kūlana hana Hastelloy C-4:

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

1, I ke kaʻina hana hoʻomehana, ʻaʻole hiki ke hoʻopili ʻia me ka sulfur, phosphorus, kēpau a me nā metala haʻahaʻa haʻahaʻa, a i ʻole e lilo ka hui i mea palupalu, pono e makaʻala e wehe i nā mea e like me ka pena māka, ka pena hōʻike mahana, nā peni kala, nā lubricants, ka wahie a me nā lepo ʻē aʻe. ʻO ka haʻahaʻa o ka nui o ka sulfur o ka wahie, ʻoi aku ka maikaʻi, ʻo ka nui o ka sulfur o ke kinoea kūlohelohe e emi iho ma mua o 0.1%, a ʻo ka nui o ka sulfur o ka ʻaila kaumaha e emi iho ma mua 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 pololei i ka mahana a maʻemaʻe ke kinoea umu. Inā lawa ka maʻemaʻe o ke kinoea o ke kapuahi kinoea, hiki iā ʻoe ke koho.
2, ʻo ka pae mahana hana wela o ka metala o 1080 ℃ ~ 900 ℃, ʻo ke ʻano hoʻomaʻalili no ka hoʻomaʻalili wai a i ʻole ka hoʻomaʻalili wikiwiki ʻē aʻe. No ka hōʻoia ʻana i ke kūpaʻa maikaʻi loa i ka palaho, pono e mālama ʻia ka mālama wela ma hope o ka mālama wela ʻana o ka hopena.
