E like me ka mea i manaʻo ʻia mai kona ʻike keleawe kiʻekiʻe, ua hoʻouka koke ʻia ka alloy 400 e ka nitric acid a me nā ʻōnaehana amonia.
ʻO Monel 400 ka waiwai mechanical nui ma nā mahana subzero, hiki ke hoʻohanaʻia i nā mahana a hiki i ka 1000 ° F, aʻo kona helu hoʻoheheʻeʻana he 2370-2460 ° F. Eia naʻe, he haʻahaʻa ka ikaika o ka alloy 400 i ke kūlana annealed no laila, keʻano o ka huhū. hiki ke hoʻohana ʻia e hoʻonui i ka ikaika.
Nā hiʻohiʻona
ʻO ka pale ʻana i ka corrosion ma kahi ākea o ka moana a me nā kaiaola kemika.Mai ka wai maʻemaʻe i nā ʻakika mineral non-oxidizing, nā paʻakai a me nā alkali.
ʻOi aku ke kūpaʻa o kēia alloy i ka nickel ma lalo o nā kūlana hoʻohaʻahaʻa a ʻoi aku ke kūpaʻa ma mua o ke keleawe ma lalo o nā kūlana oxidizing, ʻoi aku ka maikaʻi o ke kūʻē ʻana i ka hoʻohaʻahaʻa ʻana i ka media ma mua o ka oxidizing.
ʻO nā waiwai mechanical maikaʻi mai nā mahana subzero a hiki i kahi 480C.
Kūleʻa maikaʻi i ka sulfuric a me ka hydrofluoric acid.ʻO ka aeration naʻe e hopena i ka piʻi ʻana o ka corrosion rate.Hiki ke hoʻohana ʻia no ka mālama ʻana i ka waika hydrochloric, akā ʻo ka loaʻa ʻana o nā paʻakai oxidizing e wikiwiki loa i ka hoʻouka kaua.
Hōʻike ʻia ke kūʻē ʻana i nā paʻakai kūʻokoʻa, alkaline a me ka waikawa, akā ʻike ʻia ke kūpaʻa maikaʻi ʻole me nā paʻakai waikawa oxidizing e like me ka ferric chloride.
Kūʻē maikaʻi i ka chloride ion stress corrosion cracking.
