Incoloy 825 (Nickel Alloy 825 / UNS N08825) ʻAi ʻino-Papa Nikela Alloy a me Tube - BLOG

Introduction: Alloy Advanced for Harsh Chemical Environment

Incoloy 825, i ʻike ʻia ʻoʻAi Nikela 825a i ʻoleUNS N08825, he hana -kiʻekiʻenickel–iron–chromium alloyhoʻonui ʻia memolybdenum, keleawe, a me ka titanium.
Hoʻonohonoho pono ʻia e hana ma laloʻakika, chloride, a me -mea wela wela kiʻekiʻe, e hana ana ia i kekahi o nā mea hana maʻalahi loa i nā ʻōnaehana kemika, petrochemical, a me ka ʻōnaehana kai.

Hōʻike ka alloy i kahi hui like ʻole o nā waiwai:

Kūʻē maikaʻi ihoʻoemi a hoʻohemo i nā ʻakika(me ka sulfuric a me ka phosphoric acid).
Kiʻekiʻe paʻa kū'ēlua, ʻinoʻino, a me ke koʻikoʻi-ka pohā.
Hana maikaʻi ma hopewiliwili a i ʻole ka ʻike lōʻihii nā wela kiʻekiʻe.

ʻO kona hilinaʻi ua hana ʻo Alloy 825 i mea makemake nonā mea hoʻololi wela, nā condensers, nā evaporators, a me nā paipu ma waho, kahi e noho pū ai ka corrosion a me ka luhi mechanical.

Hoʻohui Kemika a me ka Paʻa Paʻa

ʻO ka hana o Alloy 825 ka mea i hoʻokumu ʻia mai kāna ʻano hoʻohālikelike pono:

ʻElemu	Maʻiʻo (%)	Hana Metallurgical
Nikela (Ni)	38.0 – 46.0	ʻO ke kūpaʻa ʻana o ka corrosion, ke kūpaʻa o ka hale
Chromium (Cr)	19.5 – 23.5	Ke kū'ē o ka oxidation, hoʻokumu kiʻiʻoniʻoni passive
Hao (Fe)	Kaulike	Matrix kūkulu no ka paʻakikī
Molybdenum (Mo)	2.5 – 3.5	Ke kū'ē i ka ho'ēmiʻana i ka media a me ka pitting
Ke keleawe (Cu)	1.5 – 3.0	Hoʻomaikaʻi i ka pale ʻana i ka sulfuric a me ka phosphoric acid
Titanium (Ti)	0.6 – 1.2	Hoʻopaʻa kūʻē i ka corrosion intergranular
