ASTM B463 Alloy 20 Phaj Loj:
Thickness:ASTM B463 Alloy 20 daim hlautuaj yeem tsim nyob rau hauv qhov tuab ntawm 0.1875 nti (4.76 mm) txog 4.000 ntiv tes (101.6 mm).
Dav: Qhov dav ntawm2.4660 Alloy 20 daim hlautuaj yeem ncav cuag 48 ntiv tes (1219.2 hli).
Length: Qhov ntev ntawmKws ntoo 20 plamtuaj yeem ncav cuag 144 nti (3657.6 mm).
ASTM B463 UNS N08020 Daim Ntawv Pom Zoo:
Tus qauv feem ntau qhia txog qhov ntev rau qhov ntev xws li thickness, dav, thiab ntev kom ntseeg tau cov khoom sib xws thiab zoo. Cov kev tolerances no yuav txawv nyob ntawm seb cov kev cai tshwj xeeb ntawm daim ntawv thov thiab cov txheej txheem tsim khoom. Nws yog ib qho tseem ceeb kom xa mus rau qhov tseeb version ntawmASTM B 463 3rau qhov tshwj xeeb kam rau ua qhov tseem ceeb thiab cov txheej txheem.
