Dab tsi yog alloy 800H khoom?
Cov yam ntxwv dav dav
Alloy 800H (UNS N08810) thiab 800HT (UNS N08811) yog ob daim ntawv pov thawj nickel-hlau-chromium cov ntaub ntawv uas tiv thaiv oxidation, carburization thiab lwm yam kub corrosion. Cov tshuaj muaj pes tsawg leeg ntawm ob qho tib si alloys yog tib yam li Alloy 800 (UNS N08800), tab sis cov ntsiab lus carbon siab dua nyob rau hauv ob qib - (0.05-0.10%) hauv Alloy 800H thiab (0.06-0.10%) hauv Alloy 800HT. Alloy 800HT kuj tau ntxiv txhuas thiab titanium txog li 1.0%. Ntxiv nrog rau cov kev txwv tshuaj, ob qho tib si alloys tau txais kev kub ntxhov los tsim qhov nruab nrab ntawm cov nplej loj ntawm ASTM 5 lossis coarser. Cov tshuaj txwv tsis pub muaj kev sib xyaw ua ke nrog kev kub siab annealing ua kom cov ntaub ntawv no muaj kev nkag siab ntau dua thiab ua kom tawg tau zoo dua piv rau Alloy 800.
Alloy 800H muaj cov khoom tawg zoo ntawm qhov kub siab tshaj 1100 degree F (600 degree ). Vim tias qhov siab tshaj plaws titanium thiab txhuas cov ntsiab lus ntawm 0.7%, nws tseem nyob rau lub sijhawm siv mus ntev ntawm qhov kub hauv qab 1290 degree F (700 degree). Standard annealed Alloy 800 yog pom zoo rau siv nyob rau hauv kub hauv qab no 1100 degree F (600 degree). Alloy 800H yog resistant rau txo, oxidizing thiab nitriding atmospheres, raws li zoo raws li alternating txo thiab oxidizing atmospheres. Lub alloy tseem nyob ruaj khov thaum lub sij hawm ntev siv kub.
Alloy 800HT muaj lub zog zoo heev ntawm qhov kub siab tshaj 1290 degree F (700 degree). Alloy 800H yuav tsum tau siv yog tias daim ntawv thov cuam tshuam nrog kev mus ncig ntau zaus hauv qab 1290 degree F (700 degree) lossis yog tias cov khoom tivthaiv raug kub qis dua 1290 degree F (700 degree ). Qhov kub tsis kam ntawm Alloy 800HT yog sib npaug ntawm Alloy 800H. Nws tseem tuaj yeem nyob ruaj khov hauv kev siv lub sijhawm ntev ntev.
Alloys 800H thiab 800HT tau yooj yim welded thiab machined los ntawm cov qauv khw fabrication xyaum.
