Hauv kev ua haujlwm siab -kub engineering, "heat resistance" yog ib qho txuas ntxiv. Rau kev yuav cov thawj coj thiab cov neeg tsim khoom thermal, qhov teeb meem nyuaj tshaj plaws yog cov khoom muag muag (tshaj - laus).
Qhov teeb meem:Muaj ntau qhov project default rauGH3030 (sib npaug rau Nimonic 75)vim nws zoo heev oxidation kuj. Txawm li cas los xij,HWM 3030yog ib qho yooj yim npib tsib xee -chromium-titanium alloy. Thaum kub tshaj850℃(1562℃F), lub matrix poob nws mechanical "rigidity." Qhov tshwm sim? Lub tshuab hluav taws xob hauv ob sab phlu warping, radiant tube sagging, thiab poob ntawm cov qauv kev ncaj ncees nyob rau hauv combustion Cheebtsam.
hwv 3044yog tsim tshwj xeeb rau "siab-kub cheeb tsam" thiab yog ib qho tseem ceeb hloov khoom siv rau tej yam kev mob ntawm900℃thiab 1000 degree, muab kev lag luam durability unattainable los ntawm cov qauv alloys.

GH3030 thiab GH3044 Alloy Tubes: Cov Lus Qhia Ua Haujlwm Kub Kub
GH3030 thiab GH3044 yog npib tsib xee-chromium raws li cov kuab tshuaj ntxiv zog superalloys, dav siv nyob rau hauv siab -kub aerospace thiab industrial teb. Ob leeg muaj oxidation kuj zoo heev, tab sis GH3044 muaj qhov kub thiab txias ua haujlwm ntau dua li GH3030.
Dab tsi yog cov khoom ntawm GH3030?
GH3030 yog ib qho kev daws teeb meem ntxiv dag zog rau siab - kub alloy, feem ntau yog tsim los ntawm npib tsib xee (Ni) thiab chromium (Cr), nrog rau cov tshuaj lom neeg yooj yim. Nws qhov piv txwv yog 80% npib tsib xee thiab 20% chromium.
