Iithegi zeMveliso

4J36 (Invar) isetyenziswa apho uzinzo oluphezulu lufuneka khona, olufana nezixhobo ezichanekileyo, iiwotshi, iigeyiji zokurhubuluza kwenyikima, iifreyimu zesigqubuthelo semaski zikamabonwakude, iivalvu kwiimotor, kunye newotshi ye-antimagnetic. Kuvavanyo lomhlaba, xa kufuneka kwenziwe umgangatho wokuqala (high-precision) womgangatho wokuphakama, abasebenzi beNqanaba (leveling rod) basetyenziswa.Invar, endaweni yomthi, i<em>fiberglass, okanye ezinye iintsimbi. I-Invar struts isetyenziswe kwezinye iipiston ukukhawulela ukwanda kwe-thermal ngaphakathi kweesilinda zazo.

I-4J36 isebenzisa i-oxyacetylene welding, i-arc ye-arc yombane, i-welding kunye nezinye iindlela ze-welding. Ekubeni i-coefficient yokwandisa kunye nokwakheka kweekhemikhali ze-alloy inxulumene kufuneka igwenywe ngenxa ye-welding ebangela utshintsho kwi-alloy composition, kungcono ukusebenzisa i-Argon arc welding filler metals ekhethwayo iqulethe i-0.5% ukuya kwi-1.5% titanium, ukwenzela ukuba ukunciphisa i-weld porosity kunye nokuqhekeka.

Inkqubo yonyango lokushisa
I-Anealing yokunciphisa uxinzelelo	Ukufudumala ukuya ku-530 ~ 550ºC kwaye ubambe i-1 ~ 2 h. Kuyabanda
ukuhlamba	Ukuze kupheliswe ukuqina, okuveliswe kwinkqubo yokuzoba epholileyo, ebandayo. I-Annealing ifuna ukufudunyezwa kwi-830 ~ 880ºC kwi-vacuum, bamba i-30 min.
Inkqubo yozinziso	Kwimidiya ekhuselayo kwaye ishushu kwi-830 ºC, bamba i-20min. ~ 1h, cima Ngenxa yoxinzelelo olwenziwa ngokucinywa, ukufudumala ukuya kwi-315ºC, bamba i-1 ~ 4h.
Ukulumkela	Ayinakuqiniswa ngonyango lobushushu Ukunyangwa komphezulu kunokuqhunyiswa kwesanti, ukupolisha okanye ukuchola. Ingxubevange ingasetyenziswa 25% hydrochloric acid pickling isisombululo kwi 70 ºC ukucima umphezulu oxidized.
