He kūpaʻa maikaʻi loa ka alloy i ka nui o nā media corrosive ma nā mokuʻāina oxidized a hoʻemi ʻia.Kūleʻa maikaʻi loa i ka lua, crevice a me ke koʻikoʻi i ka pohā ʻino.Ua kūpono ka alloy no ka hoʻohana ʻana i nā ʻano ʻoihana kaʻina hana kemika i loaʻa i ka oxidizing a me ka hoʻohaʻahaʻa ʻana i ka media.ʻO ka maʻiʻo kiʻekiʻe o ka molybdenum a me ka chromium e hoʻoikaika i ka paʻa i ka corrosion o nā ion chloride, a ʻo ka mea tungsten e hoʻomaikaʻi hou i kona kūpaʻa ʻana.ʻO Hastelloy C-276 kekahi o nā mea liʻiliʻi e hiki ke pale aku i ka ʻino o ka chlorine moist, hypochlorite a me chlorine dioxide solutions.hao a me ke keleawe chloride).
ʻO Hastelloy C276 kahi mea nickel-molybdenum-chromium-tungsten alloy me ka pale ʻana i ka corrosion maikaʻi a me ka machinability maikaʻi.ʻOiai loaʻa iā ia ke kūpaʻa oxidation maikaʻi a hiki i 1800 ° F, ʻaʻole ʻōlelo ʻia ʻo Hastelloy C276 no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe.
Kūleʻa ʻo Nickel alloy C-276 i ka hoʻokumu ʻana i nā palena o ka palaoa i loko o ka wahi i hoʻopili ʻia i ka wela o ka hoʻoheheʻe ʻana, e lilo ia i mea moho no ka hapa nui o nā noi hana kemika a me ka petrochemical ma lalo o nā kūlana wili.ʻO ka HC276 he nickel alloy me ke kū'ē maikaʻi loa i ka hoʻohaʻahaʻaʻana i nāʻakika, sulfuric acid, hydrochloric acid, brine solutions, oxidizing chlorides a me ka wai wela.
ʻO Hastelloy C276 kekahi o nā mea liʻiliʻi e kūʻē i ka chlorine pulu, hypochlorite a me ka chlorine dioxide.ʻO kēia huila nickel kūikawā he kūpaʻa maikaʻi loa i ka crevice a me ke koʻikoʻi o ka corrosion crack, a me ka chloride pitting.ʻO kāna haʻahaʻa kalapona haʻahaʻa e hōʻemi i ka ua carbide i ka wā wili a mālama i kona kūpaʻa maikaʻi loa.'O ia ho'i, hiki i ka C-276 ke hana ma'alahi ma ka ho'ohana 'ana i nā ala e like me ka nickel-based alloys.
ʻO Hastelloyc-276 Nā ʻāpana noi no ka hoʻohana ʻana
Ua hoʻohana nui ʻia ka alloy C276 i nā māla kemika a me ka petrochemical, e like me nā ʻāpana a me nā ʻōnaehana catalytic e pili ana me nā mea kūlohelohe i loko o ka chlorine.ʻOi aku ka maikaʻi o ka mea no ka wela kiʻekiʻe, ka waika inorganic a me ka waikawa organik i hui pū ʻia me nā mea haumia (e like me ka formic acid, acetic acid), ka ʻona wai kai.
ʻO HASTELLOY C-276 he kūpaʻa maikaʻi loa i nā ʻano kaʻina hana kemika, me ka thermally polluted inorganic acids, ferric and copper chlorides, solvents, chlorine and chlorine polluted organic and inorganic pollutants, dry chlorine, acetic anhydride, Formic a me acetic a me nā wai kai. ʻO nā hāʻina brine, nā hāʻina chlorine dioxide a me ka hypochlorite.
