FeNi Nickel Hlau alloy precision 0.5 hliInvar 36 Hlaurau Sealing Precision Instrument

NTUA 36yog ib tug npib tsib xee-hlau, tsawg 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 tau zoo zog thiab toughness ntawm cryogenic kub.

NTUA 36tuaj yeem ua tau 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.

Cov txheej txheem kev kho cua sov
Annealing rau kev ntxhov siab	Kub rau 530 ~ 550ºC thiab tuav 1 ~ 2 teev. Txias cia
annealing	Nyob rau hauv thiaj li yuav tshem tawm hardening, uas yuav tsum tau coj tawm nyob rau hauv txias-dov, txias txheej txheem. Annealing xav tau cua sov rau 830 ~ 880ºC hauv lub tshuab nqus tsev, tuav 30 feeb.
Cov txheej txheem stabilization	Hauv kev tiv thaiv xov xwm thiab cua sov rau 830 ºC, tuav 20 feeb. ~ 1 h, te Vim qhov kev ntxhov siab tsim los ntawm quenching, rhuab mus rau 315ºC, tuav 1 ~ 4h.
Cov kev ceev faj	Tsis tuaj yeem hardened los ntawm kev kho cua sov Kev kho deg tuaj yeem yog sandblasting, polishing lossis pickling. Alloy tuaj yeem siv 25% hydrochloric acid pickling tov ntawm 70 ºC kom tshem tawm oxidized nto
