Cov Cim Npe Khoom

4J36 (Invar) siv rau qhov twg xav tau kev ruaj khov siab, xws li cov cuab yeej siv precision, moos, seismic creep gauges, television shadow-mask frames, valves hauv motors, thiab antimagnetic watches. Hauv kev soj ntsuam av, thaum yuav tsum ua qhov siab theem thawj zaug (high-precision) leveling, tus neeg ua haujlwm Level (leveling rod) siv yog ua los ntawmInvar, es tsis txhob siv ntoo, fiberglass, lossis lwm yam hlau. Invar struts tau siv rau hauv qee lub pistons los txwv lawv qhov kev nthuav dav thermal hauv lawv lub tog raj kheej.

4J36 siv oxyacetylene vuam, hluav taws xob arc vuam, vuam thiab lwm yam kev vuam. Vim tias qhov coefficient ntawm kev nthuav dav thiab cov tshuaj lom neeg muaj feem cuam tshuam nrog cov hlau sib xyaw yuav tsum tsis txhob raug vuam vim tias kev vuam ua rau muaj kev hloov pauv hauv cov khoom sib xyaw, nws yog qhov zoo dua los siv argon arc vuam vuam cov hlau filler uas muaj 0.5% txog 1.5% titanium, kom txo qhov vuam porosity thiab tawg.

Cov txheej txheem kho cua sov
Kev ua kom sov rau kev txo kev ntxhov siab	Kub txog 530 ~ 550ºC thiab tuav 1 ~ 2 teev. Txias cia
kev ua kom sov	Yuav kom tshem tawm cov tawv tawv, uas yuav tsum tau coj tawm hauv cov txheej txheem txias-dov, txias kos duab. Annealing xav tau cua sov rau 830 ~ 880ºC hauv lub tshuab nqus tsev, tuav 30 feeb.
Cov txheej txheem kev ruaj khov	Hauv cov khoom siv tiv thaiv thiab cua sov rau 830 ºC, tuav 20 feeb. ~ 1 teev, tua hluav taws Vim yog qhov kev ntxhov siab tsim los ntawm kev quenching, rhuab mus rau 315ºC, tuav 1 ~ 4 teev.
Cov kev ceev faj	Tsis tuaj yeem ua kom tawv los ntawm kev kho cua sov Kev kho qhov chaw tuaj yeem yog xuab zeb blasting, polishing lossis pickling. Cov hlau nplaum siv tau 25% hydrochloric acid pickling kua ntawm 70 ºC kom tshem tawm cov oxidized nto
