Incoloy 800H vs. Incoloy 800HT: Dab tsi yog qhov txawv?
Nyob rau hauv lub ntiaj teb no ntawm high -kub superalloys, Incoloy 800 series- tshwj xeebIncoloy 800H (UNS N08810)thiabIncoloy 800HT (UNS N08811) Cov.-yog cov qauv kev lag luam rau cov cua sov- cov ntawv siv tiv taus. Thaum lawv sib koom tib lub hauv paus ntawm Nickel, Chromium, thiab Hlau, hloov pauv hloov pauv hauv lawv cov chemistry thiab kev ua haujlwm ua rau muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm ntev -.
1. Chemical Composition: Qhov "Al + Ti" Factor
Qhov sib txawv tseem ceeb tshaj plaws yog nyob rau hauv kev tswj hwm ntawm cov ntsiab lus alloying, tshwj xeeb yog Carbon, Aluminium, thiab Titanium.
Incoloy 800H:Khaws cov ntsiab lus carbon ntawm 0.05-0.10%. Nws yog ib qho kev daws teeb meem -kua sov- kho version ntawm qhov yooj yim Alloy 800.
Tom ntej: Incoloy 800HTNtxiv refines 800H chemistry. Nws yuav tsum tau ua keAluminium + Titanium (Al + Ti) cov ntsiab lus ntawm 0.85% txog 1.20%.
Cov lus sib piv: Cov Khoom Siv Tshuaj
| Lub ntsiab | Incoloy 800H (UNS N08810) | Incoloy 800HT (UNS N08811) Cov. |
| Nickel (Ni) | 30.0 - 35.0% | 30.0 - 35.0% |
| Chromium (Cr) | 19.0 - 23.0% | 19.0 - 23.0% |
| Cov pa roj carbon (C) | 0.05 - 0.10% | 0.06 - 0.10% |
| Al + Ti | 0.30 - 1.20% | 0.85 - 1.20% |
| Kev kho cua sov | Kev daws Annealed | Siab -Temp Solution Annealed |
Lus Cim: Kev tswj hwm nruj dua ntawm Al thiab Ti hauv 800HT ua kom lub zog muaj zog ntau dua.
2. Cov txheej txheem kho cua sov
Ob lub alloys yog tsim los rau kev pab cuam ntawm qhov kub thiab txias qhov twg creep thiab rupture yog thawj tsis ua hauj lwm mechanisms. Txawm li cas los xij, lawv qhov ntsuas kub annealing txawv:
800H:Feem ntau yog cua sov- kho ntawm1100℃thiab 1180 degree.
800 TSI:Yuav tsum muaj kev daws teeb meem ntau dua annealing kub, feem ntau ntawm1150℃thiab 1200 degree.
Qhov siab dua no -kev kho kub rau 800HT ua kom cov nplej loj dua (ASTM 5 lossis coarser), uas yog qhov tseem ceeb rau kev ua kom nkag siab zoo ntawm qhov kub siab tshaj 700℃.
3. Kev ua yeeb yam Showdown: Qhov twg zoo dua?
Thaum ob qho tib si alloys muaj kev tiv thaiv zoo heev rau oxidation, sulfidation, thiab carburization, Incoloy 800HT siv cov hlau lead hauv huab cua.
Higher Creep Repture Strength:Vim yog qhov ua tau zoo ntawm Al + Ti cov ntsiab lus, 800HT muaj qhov tsim kev ntxhov siab ntau dua li 800H ntawm qhov kub siab tshaj 1100℃F (600 degree).
Oxidation Resistance:800HT muab qhov ntev me ntsis zoo dua - lub sij hawm nto stability hauv oxidizing atmospheres.
Thermal Expansion:Ob lub alloys muaj cov coefficients zoo sib xws, tab sis 800HT tseem nyob ruaj khov dua nyob rau hauv kev sib txuas siab siab -kub kub.
4. Cov ntawv thov ib txwm
Koj yuav tsum siv cov hlau no nyob qhov twg?
Incoloy 800H:Zoo tagnrho rau cov cua sov- kho cov khoom siv, tshuaj thiab petrochemical piping, thiab cov khoom raug kub txog li 1500℃F (815℃).
Tom ntej: Incoloy 800HTQhov kev xaiv nyiam rausiab heev -kev pabcuam kub(siab dua 700℃/ 1290℃F) hauv cov chaw tsim hluav taws xob, cov khoom siv hluav taws xob, thiab lub tshuab hluav taws xob lub tshuab hluav taws xob hauv lub tshuab hluav taws xob nuclear.
Summary: Yam khoom siv twg los xaiv?
Yog tias koj daim ntawv thov muaj qhov kub qis dua 700 degree,Incoloy 800 Hfeem ntau txaus thiab tus nqi ntau dua -zoo. Txawm li cas los xij, yog tias koj cov khoom siv yuav tsum ua siab ntevruaj khov kubnrog siab mechanical stress,Incoloy 800 HTyog qhov kev nqis peev zoo tshaj plaws vim nws txoj kev txhim kho creep tsis kam thiab kev ua neej ntev.
Vim li cas Incoloy 800H / 800HT los ntawm Gnee Steel?
Raws li ib tug ua lag luam ntawm nickel-raws li alloys, peb xyuas kom meej:
Kev ua raws cai nruj:Tag nrho cov ntaub ntawv 800H / 800HT ua tau raws li ASTM B407, B408, thiab B409 tus qauv.
Tshawb xyuas Chemistry:Kev tswj hwm ntawm Al, Ti, thiab Carbon qib tau lees paub los ntawm thib peb -Lab kuaj.
Custom Forms:Muaj nyob rau hauv seamless kav, daim hlau, round bar, thiab kev cai forgings.
