ʻO Hastelloy C-4 kahi austenitic haʻahaʻa carbon nickel-molybdenum-chromium alloy.ʻO ka ʻokoʻa nui ma waena o Hastelloy C-4 a me nā ʻāpana ʻē aʻe i kūkulu mua ʻia o ke ʻano kemika like ʻo ka haʻahaʻa kalapona, silika, hao, a me ka tungsten content.Hiki i ia mea kemika ke hōʻike i ke kūpaʻa maikaʻi loa ma 650-1040 ° C, hoʻomaikaʻi i ke kū'ē i ka intergranular corrosion, a hiki iā ia ke pale aku i ka hiki ʻole o ka corrosion o ka laina a me ka weld i ka wela wela ma lalo o nā kūlana hana kūpono.
Na waiwai waiwai
●Excellent corrosion kū'ē i ka nui corrosive media, oi aku ma ka emi moku'āina.
●Oi loa localized corrosion kū'ē i waena o halides.
Kahua noi
Ua hoʻohana nui ʻia i ka hapa nui o nā māla kemika a me nā wahi wela kiʻekiʻe.Nā wahi noi maʻamau:
●Flue kinoea desulfurization nenoaiu
●Pickling and acid regeneration plant
●Acetic acid a me ka hana agrochemical
●Titanium dioxide hana (chlorine method)
●Electrolytic plating
Hana Hoowela
Hiki ke hoʻopaʻa ʻia ʻo Hastelloy C-4 e nā kaʻina hana hoʻoheheʻe like ʻole, e like me ka tungsten electrode inert gas shielded welding, plasma arc welding, manual sub-arc welding, metal shielded inert gas welding, a me ka hoʻoheheʻe ʻia inert kinoea hoʻoheheʻe ʻia.ʻOi aku ka maikaʻi o ka welding pulse arc.
Ma mua o ke kuʻi ʻana, pono ke ʻano o ka mea i hoʻohui ʻia e wehe i ka unahi oxide, nā ʻaila hinu a me nā hōʻailona hōʻailona like ʻole, a ʻo ka laulā o kahi 25mm ma nā ʻaoʻao ʻelua o ka weld e hoʻoliʻi ʻia i kahi ʻili metala mālamalama.
Me ka hoʻokomo wela haʻahaʻa, ʻaʻole ʻoi aku ka mahana o ka interlayer ma mua o 150 ° C.
