ʻO Incoloy 926 he austenitic stainless steel alloy, e like me ka 904 L alloy, me ka 0.2% nitrogen a me 6.5% molybdenum content.Molybdenum a me ka nitrogen content e hoʻonui nui i ka crevice corrosion resistance.At the same time, nickel and nitrogen can not only improve the stability, akā, e ho'ēmi i ka manaʻo e hoʻokaʻawale i ka crystallization thermal kaʻina hana a welding kaʻina ʻoi aku ka maikaʻi ma mua o ka naikokene maʻiʻo o ka nickel alloy.Loaʻa i ka 926 ke kūpaʻa corrosion i nā ion chloride ma muli o nā waiwai corrosion kūloko a me 25% nickel alloy content.ʻO nā ʻano hoʻokolohua like ʻole i ka ʻike ʻana o 10,000-70,000 PPM, pH 5-6,50 ~ 68 ℃ ka wela hana, ka limestone desulfurization island slurry e hōʻike ana he 926 alloy ka manuahi mai ka crevice corrosion a me ka pitting i ka wā hoʻokolokolo 1-2 makahiki.ʻO ka 926 alloy he kūpaʻa maikaʻi loa i ka corrosion i loko o nā pāpaʻi kemika ʻē aʻe i ke kiʻekiʻe o ka wela, ke kiʻekiʻe kiʻekiʻe o ka media, me ka sulfuric acid, phosphoric acid, acid gas, ka wai kai, ka paʻakai a me nā waikawa organik.Eia kekahi, i mea e loaʻa ai ke kūpaʻa corrosion maikaʻi loa, e hōʻoia i ka hoʻomaʻemaʻe maʻamau.

Incoloy 926 mau hiʻohiʻona:
1. He kiʻekiʻe ka bele awāwa corrosion kū'ē a hiki ke hoʻohana 'ia i loko o ka waena me ka waika.
2. Ua hōʻike ʻia ma ka hoʻomaʻamaʻa ʻana i ka maikaʻi o ka pale ʻana i ka chloride stress corrosion māwae.
3. Loaʻa i nā ʻano corrosive kaiapuni maikaʻi.
4. Ua ʻoi aku ka maikaʻi o nā waiwai mechanical o Alloy 904 L ma mua o ko Alloy 904 L.
ʻO Incoloy 926 kahi kumu ʻikepili maʻalahi i hiki ke hoʻohana nui ʻia i nā ʻoihana he nui:
•Pūnaehana pale ahi, ʻōnaehana hoʻomaʻemaʻe wai, ʻenekinia moana, ʻōnaehana hoʻoheheʻe paipu hydraulicʻO nā paipu, nā hono, nā ʻōnaehana ea i loko o nā kinoea waikawa
•ʻO nā evaporators, nā mea hoʻololi wela, nā kānana, nā mea hoʻonāukiuki, a me nā mea'ē aʻe i ka hana phosphate
•ʻO nā ʻōnaehana condensation a me nā paipu i nā mea kanu mana e hoʻohana ana i ka wai anuanu mai ka wai ʻala
•Ka hana ʻana i nā derivatives chlorinated acidic me ka hoʻohana ʻana i nā catalysts organik.
•ka hana ʻana o ka cellulose pulp bleaching agent
•ʻEnekinia Moana
•Nā ʻāpana o ka ʻōnaehana desulfurization flue gas
•Sulfuric acid condensation and separation system
•ʻO ka paʻakai kristal a me ka evaporator
•ʻO nā pahu no ka lawe ʻana i nā kinikona corrosive
•Mea hoʻoheheʻe osmosis hoʻohuli.
