ʻO Monel 400 a me Monel 405 ʻelua mau huila nickel-copper e pili kokoke ana me nā ʻano like ʻole o ka corrosion. Eia nō naʻe, aia kekahi mau ʻokoʻa ma waena o lākou:
1. Huina:
ʻO ka Monel 400 he 67% nickel a me 30% keleawe, a loaʻa i nā mea liʻiliʻi e like me ka hao, manganese a me ke silika. Ma kekahi ʻaoʻao, ua hoʻololi iki ʻia ʻo Monel 405 me ka hoʻohui ʻana o kahi liʻiliʻi (0.5-1.5%) o ka alumini. ʻO kēia hoʻohui e kōkua i ka hoʻomaikaʻi ʻana i nā waiwai mechanical o ka alloy a hoʻonui i kona ikaika. , etc.
2. Ka ikaika a me ka paakiki:
Ma muli o ka hoʻohuiʻana o ka alumini, ua hōʻikeʻo Monel 405 i ka ikaika a me ka paʻakikī kiʻekiʻe ma mua o Monel 400. ʻO kēia ka mea e kūpono aiʻo Monel 405 no nā noi e koi ana i ka ikaika a me ka paʻakikī.
3. Weldability:
Hoʻohālikelike ʻia me Monel 400, hōʻike ʻo Monel 405 i ka maikaʻi o ka weldability. ʻO ka hoʻohui ʻana o ka alumini e kōkua i ka hoʻohaʻahaʻa ʻana i ka hoʻokumu ʻana o nā carbide intergranular i ka wā wili, hoʻonui i ka weldability o ka alloy, a hoʻemi i ka hopena o nā māwae weld.
4. Noi:
Ma muli o kona kūpaʻa maikaʻi ʻana i ka corrosion, ʻoi aku hoʻi i nā kaiapuni kai, ua hoʻohana nui ʻia ʻo Monel 400 i nā ʻoihana like ʻole, me ka moana, ka hana kemika, ka aila a me ke kinoea. Hāʻawi ʻo Monel 405 i ka ikaika a me ka weldability a hoʻohana maʻamau ʻia i nā noi e like me nā shafts pump, fasteners a me nā ʻāpana valve.
5. E koho i kanaka kūikawā:
No ke kuleana no ka hoʻonohonoho ʻana a me ka hoʻonohonoho ʻana o ka drill ahie hōʻoia i ka hoʻokō maʻalahi o ka drill.
Ma ke ʻano holoʻokoʻa, ʻoiai ʻo Monel 400 a me Monel 405 ka maikaʻi o ka pale ʻana i ka corrosion, hāʻawi ʻo Monel 405 i ka ikaika a me ka weldability i hoʻohālikelike ʻia me Monel 400, e lilo ia i koho maikaʻi loa no kekahi mau noi.
