Incoloy 800H ndi mtundu wa Incoloy 800 wotentha kwambiri wokhala ndi mpweya wolamulidwa (0.05-0.10%) komanso kapangidwe kake kotsimikizika ka tirigu wabwino (ASTM 5 kapena wokhuthala) kuti ukhale wolimba komanso wopunduka pa kutentha kwakukulu. Dzina la "H" limatanthauza ntchito yopunduka ya "Kutentha Kwambiri". Mosiyana ndi Incoloy 800 wamba, yomwe ndi yoyenera kugwiritsidwa ntchito nthawi zonse pa kutentha kwakukulu, Incoloy 800H imapereka mphamvu yopunduka kwambiri pa kutentha kopitilira 815°C kudzera mu kuwongolera bwino kwa chemistry ndi kukonza kukula kwa tirigu. Izi zimapangitsa kuti ikhale chinthu chomwe chimakondedwa kwambiri pa machubu okonzanso petrochemical, zigawo za uvuni wa ethylene cracking, ndi ntchito zina zomwe zimafuna ntchito yayitali pa kutentha kwambiri.

Makhalidwe ofunikira ndi awa:

Ubwino Waukulu wa Incoloy 800H

Mphamvu Yapamwamba Yokwera-Kuphulika– Dzina la "H" limasonyeza kuti Incoloy 800H yapangidwa mwapadera kuti igwiritsidwe ntchito pozizira kwambiri. Ndi kuchuluka kwa kaboni kolamulidwa (0.05-0.10%) ndi kukula kwa tirigu (ASTM 5 kapena kolimba), Incoloy 800H imapereka mphamvu yokwera kwambiri poyerekeza ndi Incoloy 800 yokhazikika pa kutentha kopitilira 815°C. Pa 870°C, mphamvu yokwera ya maola 1,000 ndi 45 MPa — yokwera kwambiri kuposa 800 yokhazikika.

Kukana Kwambiri kwa Oxidation– Incoloy 800H imapanga sikelo ya Cr₂O₃ oxide yomatira kwambiri yomwe imapereka chitetezo chabwino kwambiri m'mlengalenga wothira okosijeni mpaka 1093°C (2000°F). Kuwonjezera kwa aluminiyamu (0.15-0.60%) kumawonjezeranso kukana okosijeni mwa kuthandizira kukhala ndi Al₂O₃ yoteteza pamalo olumikizirana achitsulo ndi okosijeni, kukonza kumamatira kwa sikelo ndikuletsa kuphulika pansi pa kutentha.

Kukula kwa Tirigu Wolamulidwa– Incoloy 800H imapangidwa ndi kukula kotsimikizika kwa tirigu wa ASTM 5 kapena wokulirapo. Kapangidwe ka tirigu wokulirapo kamachepetsa kutsetsereka kwa malire a tirigu pa kutentha kwakukulu, zomwe zimapangitsa kuti tisagwedezeke kwambiri. Ichi ndi chosiyanitsa chachikulu ndi Incoloy 800 yokhazikika, yomwe ilibe zofunikira zenizeni za kukula kwa tirigu.

Kukana kwa Carburization– M'malo okhala ndi kaboni wambiri (mauvuni ophwanyika a ethylene, osintha nthunzi), Incoloy 800H imalimbana ndi carburization bwino kuposa ma alloy ena ambiri osatentha. Izi zimaletsa fumbi lachitsulo ndi kuphulika, zomwe zimawonjezera moyo wa machubu mu ntchito ya petrochemical komwe machubu achitsulo cha kaboni amatha kulephera mkati mwa miyezi ingapo.

Kukana Kwabwino kwa Nitric Acid ndi Chlorides– Kuchuluka kwa nickel (30-35%) kumapereka kukana bwino ku ming'alu ya chloride stress corrosion, pomwe kuchuluka kwa chromium kumapereka kukana bwino kwa nitric acid, zomwe zimapangitsa Incoloy 800H kukhala yoyenera kugwiritsa ntchito zida za nitric acid.

Kutha Kusenda Bwino Kwambiri– Incoloy 800H ikhoza kulumikizidwa mosavuta pogwiritsa ntchito TIG, MIG, resistance welding, ndi njira zina zokhazikika. Kufanizira filler metal ERNiFeCr-1 (AWS A5.14) kumalimbikitsidwa. Chithandizo cha kutentha pambuyo pa weld sichifunikira pazinthu zambiri.

Mafunso Ofunsidwa Kawirikawiri

Q: Kodi kusiyana pakati pa Incoloy 800 ndi Incoloy 800H ndi kotani?

A: Incoloy 800H ili ndi mpweya wochuluka wokwanira (0.05-0.10%) ndipo imatsimikiza kukula kwa tirigu (ASTM 5 kapena wokulirapo), zomwe zimapangitsa kuti mphamvu ya creep-rupture ikhale yabwino kwambiri pa kutentha kopitilira 815°C. Standard Incoloy 800 ili ndi ≤0.10% carbon yopanda kukula kwa tirigu, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kutentha kwambiri koma yosakonzedwa bwino kuti isagwedezeke.

Q: Kodi kutentha kwakukulu kwa ntchito ya Incoloy 800H ndi kotani?

A: Pa kukana okosijeni, Incoloy 800H ingagwiritsidwe ntchito mpaka 1093°C (2000°F). Pa mphamvu ya kapangidwe kake ndi kukana kuyandama, ntchito yopitilira mpaka 870-927°C imalimbikitsidwa kutengera kuchuluka kwa kupsinjika. Pa 1000°C, alloy imapereka kukana kothandiza kwa kuyandama pa ntchito zambiri.

Q: Kodi Incoloy 800H ingathe kuwotcherera mosavuta?

A: Inde. Incoloy 800H ikhoza kulumikizidwa pogwiritsa ntchito TIG, MIG, resistance welding, ndi njira zina zokhazikika. Kufanizira filler metal ERNiFeCr-1 (AWS A5.14) kumalimbikitsidwa. Kutentha sikofunikira pa makulidwe osakwana 15mm. Pazigawo zokhuthala, chithandizo cha kutentha pambuyo pa weld chingaganizidwe kuti chibwezeretse kukana kwa creep.

Q: Kodi Incoloy 800H yofanana ndi ya ku China ndi yotani?

A: Chofanana ndi cha ku China ndi NS112. Giredi iyi ikugwirizana ndi miyezo ya GB/T 15007 ya ma alloys okhala ndi nickel.

Q: Ndi mitundu iti ya zinthu zomwe zilipo za Incoloy 800H?

A: Womic Steel imapereka Incoloy 800H mu chitoliro chopanda msoko, chitoliro cholumikizidwa, bala lachitsulo, mbale yachitsulo, coil yachitsulo, strip, flanges, zolumikizira mapaipi, forgings, ndi ma valve. Mafotokozedwe athunthu azinthu ndi kukula kwake zalembedwa mu gawo la kupezeka kwazinthu.
