Alloy 625 (UNS N06625)
Hōʻuluʻulu manaʻo	ʻO kahi huila nickel-chromium-molybdenum me ka hoʻohui o ka niobium e hana pū me ka molybdenum e hoʻopaʻa i ka matrix o ka alloy a ma laila e hāʻawi ai i ka ikaika kiʻekiʻe me ka hoʻoikaika ʻole ʻana i ka wela. ʻAʻole kūʻē ka alloy i kahi ākea ākea o nā kaiapuni koʻikoʻi a ʻoi loa ke kūpaʻa i ka pitting a me ka crevice corrosion. Hoʻohana ʻia i ka hana kemika, aerospace a me ka ʻenekinia moana, nā mea hoʻomalu pollution, a me nā reactors nuklea.

Microstructure

ʻO ka Alloy 625 kahi huila paʻa-solution matrix-stiffened face-centered-cubic alloy.
Nā huaʻōlelo

Ma muli o kāna mau pahu pahu haʻahaʻa a me ka mālama ʻana i ka wela, hōʻike ʻo Inconel 625 i ka manaʻo liʻiliʻi i ka sensitization ʻoiai ma hope o 50 hola i nā mahana ma ka laulā 650 ~ 450 ℃.

Hāʻawi ʻia ka alloy i loko o ke kūlana palupalu palupalu no nā noi e pili ana i ka corrosion pulu (Alloy 625, papa 1), a ua ʻae ʻia e TUV no nā moku kaomi i ka pae wela -196 a 450 ℃.

No nā noi wela kiʻekiʻe, ma luna o ka approx. 600 ℃ ， kahi e koi ʻia ai ka ikaika kiʻekiʻe a me ke kūʻē ʻana i ke kolo a me ka haki ʻana, hoʻohana maʻamau ka hoʻohana ʻana i kahi hopena-annealed version (Alloy 625, grade 2) me kahi ʻona kalapona kiʻekiʻe a loaʻa i ke noi ma kekahi mau huahana huahana.

Kū'ē kū'ē i ka lua, ka ʻinoʻino, a me ka hoʻouka kaua intergranular;

Kokoke piha loa mai ka chloride-induced stress-corrosion pohā;

ʻO ke kūpaʻa maikaʻi i nā ʻakika mineral, e like me ka nitric, phosphoric, sulfuric a me nā waikawa hydrochloric;

Kūleʻa maikaʻi i nā alkalis a me nā waikawa organik;

ʻO nā waiwai mechanical maikaʻi.
Pale ʻino

ʻO ke kiʻekiʻe o ka alloy alloy 625 e hiki ai iā ia ke pale i nā ʻano ʻano ʻano ʻino koʻikoʻi. Ma nā wahi ʻoluʻolu e like me ka lewa, ka wai hou a me ke kai, nā paʻakai kūʻokoʻa, a me nā media alkaline ʻaneʻane ʻaʻohe hoʻouka. I loko o ka pōʻino koʻikoʻi, ʻo ka hui pū ʻana o ka nickel a me ka chromium hāʻawi i ke kūʻē ʻana i ka kemika oxidizing, ʻoiai ʻo ka nickel kiʻekiʻe a me ka molybdenum i loko e hāʻawi i ke kūʻē ʻana i ka nonoxidizing e kūʻē i ka sensitization i ka wā wili, a laila e pale ai i ka pohā intergranular ma hope. Eia kekahi, hāʻawi ka ʻike nickel kiʻekiʻe mai ka chloride ion-stress-corrosion cracking.
Nā noi

ʻO ka mana palupalu o Alloy 625 (papa 1) makemake ʻia no nā noi i ka ʻoihana kaʻina hana kemika, i ka ʻenekinia moana a me nā lako hoʻomalu pollution no ka pale ʻana i ke kaiapuni. ʻO nā noi maʻamau:

1. Superphosphoric acid hana lako;

2. ʻO nā lako hana hoʻoheheʻe nuklea;

3. ʻO nā paipu hana kinoea ʻawaʻawa;

4. Pūnaehana paipu a me ka uhi o nā risers i ka ʻimi ʻaila;

5. ʻO ka ʻoihana waho a me nā lako kai;

6. ʻO nā mea hoʻoheheʻe kinoea a me nā mea damper;

7. ʻO nā lining chimney.
No ka noi wela kiʻekiʻe, a hiki i ka 1000 ℃, hiki ke hoʻohana ʻia ka hopena-annealed version o Alloy 625 (papa 2) e like me ke code ASME no nā moku kaomi. ʻO nā noi maʻamau:

 

1. Nā ʻāpana o ka ʻōnaehana kinoea a me nā mea kanu hoʻomaʻemaʻe kinoea i ʻike ʻia i nā wela kiʻekiʻe;

2. Hoʻopaʻa ahi i loko o nā mea hoʻoheheʻe a me nā paepae waho;

3. Recuperator a me compensators;

4. Submarine diesel engine exhaust system;

5. ʻO nā paipu superheater i nā mea kanu ʻōpala.
