Ma nā kūlana hana koʻikoʻi o ka ʻenekinia kemika, ka mana nuklea a me nā māla ʻē aʻe, ua lilo ʻo Incoloy 800HT i mea hōkū i ka ʻoihana moku kaomi ma muli o kāna "kūʻai wela kiʻekiʻe, pale ʻana i ka corrosion a me ka ikaika kiʻekiʻe" hana trinity. I kēia lā, e noʻonoʻo hohonu mākou i ka "genetic code" a me nā mana kūpono o kēia alloy!

 

I. Hoʻohui Kemika: ʻO ke ʻano o ka Alloy pololei

 

ʻO ke kumu o Incoloy 800HT i haku ʻia me ka nickel, chromium, a me ka hao, me ka lele ʻana o ka hana i loaʻa ma o ka mana pololei o nā mea trace:

hehee ai	Laulā maʻiʻo(%)	Hana kumu
Nikela (Ni)	30.0 - 35.0	Hoʻokumu i kahi matrix austenitic, e kū'ē ana i ka oxidation wela a me ka carburization
Lāhouhea (Cr)	19.0 - 23.0	Hoʻopuka i kahi kiʻiʻoniʻoni pale Cr₂O₃, kūʻē i ka ʻino a me ka sulfidation
Laʻi (Fe)	≥ 39.5 (kaulike)	Hoʻemi i ke kumu kūʻai waiwai a hoʻonui i ka hana wela
Kalepona (C)	0.06 - 0.10	Hoʻokumu i nā carbide me Al a me Ti, e hoʻonui ana i ka pale ʻana i nā kolo
Aluminum + Titanium (Al + Ti)	0.85 - 1.20	ʻO ka hoʻoikaika ʻana i nā palena o ka palaoa i ka synergy, e mālama ana i ke kūpaʻa o ke kūkulu ʻana i nā wela kiʻekiʻe

 

Manaʻo Manaʻo: Ma o ka synergy ternary o ke kalapona, aluminika, a me ka titanium, 800HT hana i kahi γ 'phase paʻa (Ni₃(Al,Ti)) i nā wela kiʻekiʻe, me ke kūpaʻa creep ʻoi aku ma mua o ʻekolu mau manawa o ke kila kila maʻamau.

 

II. Nā Pono Mechanical: "Ka ikaika ikaika" ma nā wela kiʻekiʻe

 

1. Nā Waiwai Mahanahana lumi (Solution Annealed State)

- Ka ikaika tensile: 450-580 MPa (1.5 manawa o ke kila maʻamau)

- Elongation: 30% -45% (ʻO ka plasticity maikaʻi e hōʻoia i ka formability)

- Paʻa Paʻakikī: Axial ≥ 150 J/cm² (Ke kūʻē kūʻē i ka haki ʻana)

 

2. Nā Waiwai Kiekie (Ma luna o 700°C)

- Kū'ē Kūlohelohe: Ka ikaika haʻihaʻi ≥ 32 MPa ma hope o 1000 hola ma 870°C

- Thermal Stability: Mālama i ka pono o ke kiʻi oxide ma hope o ka hoʻohana lōʻihi ma 980 ° C

- Coefficient of Thermal Expansion: 13.3×10⁻⁶/°C (20-100°C), e hōʻemi ana i ka pōʻino koʻikoʻi wela.

Hoʻohālikelike Hoʻohālikelike: Ma 800 ° C, ʻehā mau manawa o ka ikaika o 800HT ma mua o ka 304 stainless steel, a ua hoʻonui ʻia kona ola lawelawe e 5-8 mau makahiki.

 

III. ʻO ka "ʻEkolu Front" o ka ʻoihana ʻoihana paʻi

 

1. Nā "Kāi" o nā Reactors Kiʻekiʻe

- Ethylene Cracking Furnaces: E kū i nā mahana a hiki i 900 ° C a me nā kaiapuni hydrogen, e hoʻololi ana i ke kila kila 310S kuʻuna, a e hoʻonui i ke ola o nā mea hana i ʻekolu manawa.

- Nā Reactors Hydrogenation: Kū'ē i ka hydrogen embrittlement a me ka sulfur corrosion ma 15 MPa kiʻekiʻe-pressure a me ka H₂S-i loko o ka media, e hōʻemi ana i nā helu hemahema e 70%.

 

2. ʻO nā "Paʻa Palekana" o nā mea kanu Nukelea

- Nā Paipu Hoʻoili Wela ʻO ka Mokumahu: Hoʻokō i nā kūlana nuklea ASME SB-407, kūpaʻa i ka hoʻoheheʻe ʻana i ka mahu a me ka corrosion stress.

- Nā Lako Lapaʻau Nuclear Waste: E hoʻomau i ka paʻa i ka nitric acid a me ka media fluoride, me ke ola lawelawe ʻoi aku ma mua o 20 mau makahiki i nā kaiapuni radiation.

 

3. ʻO nā "Mainstays o ka wā e hiki mai ana" o nā lako ikehu hou

- Nā Waʻa Hoʻopaʻa Hydrogen: Me ka pālua o ka hydrogen permeation resistance o 316L, e hoʻomaʻamaʻa i ka mālama ʻana i ka ikehu maʻemaʻe.

- Supercritical CO₂ Pūnaehana Hoʻoulu Mana: Ma lalo o 650°C/25 MPa kūlana, ʻoi aku ka ikaika o ka waiwai ma lalo o 5%.

 

Panina

ʻO ka hānau ʻana o Incoloy 800HT e hōʻike ana i ka ʻoiaʻiʻo "ʻo ka ʻepekema waiwai e hoʻoikaika i ka holomua ʻoihana." Mai ka hoʻokumu pololei ʻana i loko o ke keʻena hana a hiki i ka hoʻoheheʻe ʻana i nā tausani degere i loko o ka hale hana, ke hoʻololi hou nei kēia huila i nā palena hana o nā moku kaomi wela kiʻekiʻe!

 

Loaʻa iā Vigor ka ʻike nui i ka hana ʻana i nā Incoloy alloy die-forgings a me ka post-treatment. Inā he mau nīnau kāu, nā koi, pono e hoʻomohala ʻia nā ʻāpana hou a i ʻole e hoʻomaikaʻi i kāu kaulahao lako, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou ma info@castings-forging.com
