Qhov txawv ntawm Incoloy 800, 800H thiab 800HT

Kev 800, 800H, thiab 800HT yog npib tsib xee-hlau-chromium alloys paub txog lawv lub zog zoo thiab zoo heev tiv thaiv oxidation thiab carburization nyob rau hauv high-temperature raug. Lawv qhov sib txawv yog nyob rau hauv cov tshuaj muaj pes tsawg leeg, siab kub lub zog, thiab cov qauv ntawv pov thawj.

Tshuaj muaj pes tsawg leeg:

Kev 800: Nickel ({0}}%), chromium (19-23%), hlau (sib npaug).

Nws kuj muaj cov pa roj carbon tsawg (txog 0.10%), manganese, silicon, thiab tooj liab.

Incoloy 800 H: Zoo ib yam li Incoloy 800 tab sis nrog cov ntsiab lus carbon ntau dua (0.05-0.10%) ,

thiab tswj nruj dua aluminium thiab titanium cov ntsiab lus (0.30-1.20%).

Incoloy 800 HT: Shares tib cov ntsiab lus carbon li 800H,

tab sis nrog ntxiv ncethiab tswj nruj nreem aluminium thiab titanium cov ntsiab lus (0.85-1.20%).

High-Temperature Strength:

Kev 800: Feem ntau yog siv rau cov ntawv thov qis dua 1100 ℉.

Incoloy 800 H: Feem ntau yog siv rau cov ntawv thov kub siab tshaj 1100℉ xav tau kev tiv thaiv rau kev nkag thiab tawg.

Qhov sib npaug ntawm cov tshuaj muaj pes tsawg leeg muab cov nickel-steel alloys zoo heev rau carburization, oxidation, thiab nitridation.

Incoloy 800 HT: Tsis txhob nkim txawm tias tom qab siv mus ntev li ntawm 1200-1600℉ ntau yam,tsis zoo li ntau cov hlau tsis muaj steel uas zoo li ua nkig hauv qhov ntsuas kub no.

Nws nthuav tawm cov txheej txheem txias txias zoo ib yam ntawm cov nickel-chromium alloys. Qhov tseem ceeb ntawm qhov txias txias tuaj yeem ua rau pom pom cov ciam teb nto ripples hu ua "txiv kab ntxwv tev." Incoloy 800HT tuaj yeem welded siv cov txheej txheem ntau rau stainless hlau.

Certification thiab Standards:

Tag nrho peb cov alloys ua raws li ASTM cov qauv, tab sis 800H thiab 800HT feem ntau muaj kev tswj hwm nruj dua kom ntseeg tau tias kev ua haujlwm ntawm qhov kub thiab txias.Cov ntsiab lus npib tsib xee muab kev ua haujlwm siab rau chloride kev nyuaj siab corrosion cracking thiab brittleness vim sigma theem nag lossis daus.Feem ntau, lawv muaj zoo heev corrosion kuj.

Nyob rau hauv cov tshuaj-annealed mob, 800H thiab 800HT alloys pom zoo heev creep thiab kev nyuaj siab rupture zog.

Niaj hnub no, cov neeg muag khoom feem ntau, suav nrog Mega Mex, tsuas yog muab ob daim ntawv pov thawj 800H / HT alloys.

Cov ntsiab lus:

Lub ntsiab sib txawv ntawmIncoloy 800, 800H, thiab 800HTdag nyob rau hauv lawv cov carbon, aluminium, thiab titanium cov ntsiab lus. Lub dual-certified nickel alloys (800H / HT) muab cov yam ntxwv ntawm ob daim ntawv. Incoloy 800H / HT yog ib qho kev txhim kho tshaj Incoloy 800 thiab yog siv rau kev siv cov txheej txheem kub..
