FeNi Nickel Hlau Alloy Precision 0.5mm Invar 36 Hlau Rau Sealing Precision Instrument
FeNi Nickel Hlau alloy precision 0.5 hliInvar 36 Hlaurau Sealing Precision Instrument
NTUA 36yog nickel-hlau, tsis tshua muaj expansion alloy muaj 36% npib tsib xee.Nws tuav ze li qhov Dimensions Tshaj li qhov kub ntawm huab cua ib puag ncig, thiab muaj cov coefficient tsawg ntawm kev nthuav dav los ntawm qhov kub thiab txias txog li 500 ° F. Cov hlau kuj tseem khaws zoo zog thiab toughness ntawm cryogenic kub.
NTUA 36tuaj yeem kub thiab txias tsim thiab machined siv cov txheej txheem zoo ib yam li
austenitic stainless hlau.INVAR 36 yog weldable siv Filler Hlau CF36 uas yog
muaj nyob rau hauv liab qab hlau rau ob qho tib si GTAW thiab GMAW txheej txheem.
