6. Ke kohoʻana ma waena o nā alloys

E hoʻohana i kēia alakaʻi loiloi pono:

• E koho iā Monel 400 I ka wa: ʻO ke koina mua ke koiʻana i ka paleʻana, maikaʻi maikaʻi a me ka formability, a me nā koina o ka uku kūʻai aku / loaʻa i nā manaʻo noʻonoʻo maikaʻi, welloble alloy.
  Maʻamau no ka lawelawe kai kai, Nā mea hana i nā lako hana, a me ka mea nui.
• E koho i Monel K-500 i ka wā: pono oe ikaika ikaika loa ua hui pū me ka paleʻana o Corrosioni (E.g., nā'āpana kiʻekiʻe, Nā Koho Pūnaewele, nā mea paʻa kiʻekiʻe kiʻekiʻe).
  Kumu i ka pono no ka mālama wela wela a me ka hopena o ka hopena.
• E koho i nā koho koho (ʻO nā mea'ē aʻeʻo Ni-Cu a iʻole Duplex Alloys) I ka wa: Kālā, Nā waiwai magnetic, a iʻole nā ​​wahi kiko'ī (E.g., ʻO nā mea hoʻokūkū kiʻekiʻe loa, 'Oxidizing estid) e hana i kahiʻohanaʻokoʻa'ē aʻe.

8. PAHUI, Nā hopohopo kūikawā, a me nāʻano hanaʻole

• Kālā: ʻO Nickel a me nā mea kūʻai keleawe e hana ai i nā molowe nui eʻoi aku ka nui o nā mea iʻoi aku ma mua o nā mea kanu maʻamau. Pono ke kumukūʻai o ke ola-cycle ke koho i ka koho koho.
• Haz e hoʻonāukiuki i k-500: Hiki i ka uē ke hōʻemi i ka ikaika kūloko ināʻaʻole i hoʻopiliʻia ka hana wela wela.
• Slfride koʻikoʻi / nā hopena hydrogen: ʻOiaiʻo Monel e hana maikaʻi ana i nāʻano he nui, ʻO nā kūlana H₂s kūikawā a me nā Stidarios Chargenarios e nānā pono ai.
• Alohaʻo Galvanika: ʻO Monel e hoʻopili me nā metala liʻiliʻi e hiki ke hana i nā calvanic corrosionin corrosion i nā lāʻau lapaʻau o galvanic a iʻole nā ​​maʻi maʻi.
• Hōʻalo ka mea hana hewa: E koi aku i nā'āpana molena i nā hana maikaʻi loa; possy a iʻole nā ​​manaʻo e hōʻemi ai i ka morrosion a me ka hana mechanical.

9. Nā kuhi hewa maʻamau e pili ana i nā mollel

"Ua hoʻololiʻia nā hua manu āpau"

Wahahee. ʻO K-500 kaʻoi aku o ka x5X ikaika ma mua o 400 Akā he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa; ʻO R-405ʻO Sulfur e hui pū me ka machinipalibility akā hōʻemi iki iki.

Ke kū nei ke koho koho ma ka ikaika, kaʻona, a me nā mea e pono ai.

"ʻO Monel ka Corrosion-Proof i nā wahi āpau"

Wahahee. ʻO ka mollel makemake e loli i nā maʻi'oxidizing (E.g., makeihewa hn₃) a me keʻano o ke kauʻana o keʻano kiʻekiʻe (>70% kūlike).

ʻO lākou kahi e hōʻemi ai i nā wahi hōʻemi (Ke wai wai, dilite acid) akā,ʻaʻole i hanaʻia.

"ʻO Monel K-500 wale nō he mau mikina ikaika loa 400"

Kahiʻoiaʻiʻo, Akāʻo K-500 he haʻahaʻa haʻahaʻa haʻahaʻa (koi i ka post-weld iging) a ua kaupalenaʻia i 480 ° C (vsa. 550° C no 400).

He mea kū'ē paha ia, ʻoi aku ka maikaʻi no nā noi kiʻekiʻe kiʻekiʻe.

"ʻO ka pipi ka mea nui loa no ka hapa nui o nā noi"

Context-hilinaʻi. Corsel kumukūʻai 3x ma mua o 316 kila kohu ʻole, aka ona 25+ ʻO ke ola o ka lawelawe makahiki ma keʻano o ke kai e hōʻemi ana i nā kumukūʻai ola e 40-60% i hoʻohālikelikeʻia i ke kila kila (e pono ai e koho pinepine).

"ʻAʻole hiki ke hoʻopauʻia nā moll

Wahahee. ʻO nā helu mua a pau loa i hiki iā ia ke hana i nā metala filler pololei (Ercinu-7) a me ka hana wela wela (no k-500). Welded moel 400 Nā Māhele 90% o ka ikaika nui.

10. Hoʻohālikelike me nā mea'ē aʻe o Nickel

11. Hopena

ʻO ka moly Alloys e hana i kahi pono, ʻO kaʻohana hilinaʻi maikaʻi o Ni-CU mau huahana i kahi o nā mea e pono ai ka paleʻana o ka corrossion, paʻakikī a me ka ikaika.

Molol 400 ʻO ka koho koho i ka wā e kū ai ka paleʻana o ka paleʻana a me ka parability he paramika; Molnel k-500 ʻO ke koho no ka ikaika kiʻekiʻe kahi eʻaeʻia ai ka paʻakikī o ka paʻakikī o ka paʻakikī.

Nā Kūlana Kūʻai kūikawā (R-405, 502, S-Kona) noho e hoʻoponopono i ka machining, Ke kūʻai aku nei a iʻole nā ​​koina a iʻole ke kumukūʻai a me nā kumuhana mau i ka hōʻoiaʻana i ke kaiāulu.

No nā māhele koʻikoʻi, E koi mau i nā helu UN, Nā palapala hōʻoia, a kūpono kūpono ndt a me ka hōʻoia o ka corrosion.
