ʻO HastelloyC alloy kahi huila Ni-Cr-Molybdenum-Tungsten maʻalahi e hāʻawi i ka pale ʻana i ka corrosion holoʻokoʻa ma mua o nā mea ʻē aʻe o Ni-Cr-Molybdenum-Hastelloy C276, C4 a me 625 alloys.
He kūpaʻa maikaʻi loa nā alloys Hastelloy C i ka pitting, crevice corrosion a me stress corrosion crack.
He kūpaʻa maikaʻi loa ia i ka media wai hoʻoheheʻe ʻia, me ka chlorine pulu, ka waikawa nitric a i ʻole ka hui ʻana o nā waikawa oxidizing i loko o nā ion chloride.
I ka manawa like, ua loaʻa i nā alloys Hastelloy C ka mana kūpono e pale aku i ka hoʻohaʻahaʻa a me ka oxidizing kaiapuni i loaʻa i ka wā o ke kaʻina hana.
Me kēia versatility, hiki ke hoʻohana ʻia i kekahi mau wahi pilikia, a i ʻole i nā hale hana no nā kumu hana like ʻole.
He kūʻokoʻa ko Hastelloy C alloy i nā ʻano kemika like ʻole, e like me nā mea hoʻoneʻe ikaika, e like me ka ferric chloride, copper chloride, chlorine, thermal pollution solution (organic a inorganic), formic acid, acetic acid, acetic anhydride, ke kai a me ka wai paʻakai.
Hiki i ka Hastelloy C alloy ke pale aku i ka hoʻokumu ʻana o ka ua i loko o ka wahi i hoʻopili ʻia i ka wela, kahi e kūpono ai i nā ʻano hana kemika he nui i ka mokuʻāina.
