Iithegi zeMveliso

4J36 (I-Invar) isetyenziswa apho kufuneka uzinzo oluphezulu, njengezixhobo zokuchaneka, iiwotshi, iigeyiji zokuqhekeka kwe-seismic, iifreyimu zemaski yesithunzi sikamabonwakude, iivalvu kwiimoto, kunye neewotshi ezichasene nemagnethi. Ekuhlolweni komhlaba, xa kufuneka kwenziwe i-first-order (high-precision) elevation leveling level, i-Level staff (leveling rod) esetyenzisiweyo yenziwe ngeI-Invar, endaweni yomthi, i-fiberglass, okanye ezinye iintsimbi. Ii-Invar struts zazisetyenziswa kwezinye iipiston ukunciphisa ukwanda kwazo kobushushu ngaphakathi kweesilinda zazo.

I-4J36 isebenzisa i-oxyacetylene welding, i-electric arc welding, i-welding kunye nezinye iindlela ze-welding. Ekubeni i-coefficient yokwandiswa kunye nokwakheka kweekhemikhali ze-alloy kunxulumene kufuneka kuphetshwe ngenxa yokuba i-welding ibangela utshintsho kwi-alloy composition, kungcono ukusebenzisa i-Argon arc welding welding filler metals ngcono ibe ne-0.5% ukuya kwi-1.5% titanium, ukuze kuncitshiswe ukuqhekeka kwe-weld kunye nokuqhekeka.

Inkqubo yokunyanga ubushushu
Ukuncedisa ukunciphisa uxinzelelo	Ishushu ukuya kuma-530~550ºC kwaye ibambe iyure eyi-1~2. Ibanda
ukucoca	Ukuze kupheliswe ukuqina, okuza kukhutshwa kwinkqubo yokutsala ebandayo neyokuqengqeleka. Ukutsalwa kwe-Annealing kufuna ukufudunyezwa ukuya kwi-830 ~ 880ºC kwi-vacuum, gcina imizuzu engama-30.
Inkqubo yokuzinzisa	Kwi-media yokukhusela kwaye ishushu ukuya kwi-830 ºC, gcina imizuzu engama-20. ~ iyure eli-1, cima Ngenxa yoxinzelelo olubangelwa kukucima, olufudunyezwa ukuya kwi-315ºC, gcina iyure eyi-1 ~ 4.
Ukulumkela	Ayinakwenziwa lukhuni ngonyango lobushushu Unyango lomphezulu lungaba kukugquma isanti, ukupolisha okanye ukukha amanzi. I-alloy ingasetyenziswa isisombululo se-25% se-hydrochloric acid pickling kwi-70 ºC ukususa umphezulu oxidizisiweyo
