HASTELLOYC4ʻO ia ka huila i haku ʻia me Nickel, chromium, a me molybdenum. Manaʻo nui ʻia ʻo ia ka mea hoʻoheheʻe nui loa no ka hakakā ʻana i ka corrosion. Hōʻike kēia alloy i ke kūʻē ʻana i ka hoʻokumu ʻana o ka palena o ka palaoa i ka wā i hoʻopaʻa ʻia i ka wela welding, kūpono ia no nā ʻano hana kemika i kona kūlana welded. Eia hou, AlloyC4hōʻike i ke kūʻē kūʻokoʻa i ka pitting, ka pohā ʻana i ka ʻino-corrosion, a me nā ea hoʻoneʻe ʻana a hiki i 1900 ° F. Loaʻa iā ia ke kūʻē kūʻokoʻa i kahi ākea o nā kaiapuni kemika.
NĀ PALAPALA:
1. ʻOihana pepa: ʻO nā mea hoʻoheheʻe a me nā mea kanu bleach.
2. Nā ʻea kinoea ʻawaʻawa: Nā ʻāpana i ʻike ʻia i ke kinoea ʻawaʻawa.
3.Flue-gas desulfurization mea kanu: Mea hoʻohana i ka flue-ea desulfurization mea kanu.
4.Sulfuric acid environments: Evaporators, heat exchangers, filters, and mixers hoʻohana ʻia i ka sulfuric acid environments.
5.Sulfuric acid reactors: Nā mea hana i hoʻohanaʻia i nā mea hoʻoheheʻe sulfuric acid.
6.Organic chloride kaʻina: ʻO nā mea hana i hoʻohanaʻia i ke kaʻina hana chloride.
7.Halide a acid catalyst kaʻina hana: ʻO nā mea hana i hoʻohana ʻia i nā kaʻina hana e hoʻohana i ka halide a i ʻole ka waika catalysts.
