Kev sib piv ntawm GH3030 thiab GH3039 Seamless Steel Pipes
Kev sib piv ntawm GH3030 thiab GH3039 Seamless Steel Pipes
GH3030 thiab GH3039 yog npib tsib xee-raws li kev daws teeb meem ntxiv dag zog rau superalloys siv nyob rau hauv siab -kev siv kub. Vim yog qhov sib ntxiv ntawm molybdenum (Mo) thiab niobium (Nb), GH3039 feem ntau pom muaj zog thiab oxidation tsis kam ntawm qhov kub siab dua (< 1000°C), while GH3030 (continuous operating temperature < 800°C) is more suitable for low-load, high-ductility, and high-fatigue environments.
GH3039 khoom yog dab tsi?
GH3039 yog ib qho siab -kub alloy, tseem hu ua Inconel 713C. Nws yog npib tsib xee-raws li siab- kub alloy nrog zoo heev - kub lub zog, oxidation tsis kam, thiab creep kuj.

Nco tseg:GH3039 alloy yog tsim los ntawm Shenyang Institute of Metal Research hauv 1965 raws li GH3030 alloy, los ntawm kev ntxiv cov khoom xws li txhuas, titanium, molybdenum, thiab niobium los txhim kho nws lub zog. GH3030 yog ib qho yooj yim 80Ni-20Cr cov tshuaj tiv thaiv kom muaj zog alloy, thaum GH3039 yog ib qho nyuaj dua Ni-Cr-Mo-Nb-Al-Ti alloy nrog zoo heev-kub lub zog thiab tiv thaiv thermal qaug zog mus txog 05 ° C. Rau cov khoom siv seamless yeeb nkab, piv nrog cov kev qhia dav dav, GH3030 muaj kev txwv nruj dua ntawm cov ntsiab lus ntawm Fe (Less dua lossis sib npaug rau 1.0%), P (Less dua lossis sib npaug rau 0.015%), S (Less dua lossis sib npaug rau 0.010%), thiab Cu (tsawg dua lossis sib npaug li 0.007%).
