Uns K93600 Invar 36 Ribbon Precision Expansion Alloy Flat Wire
Uns K93600 Invar36 Ribone Precision Katoloso Alloy Flat Wire
(Lebitso le Tloaelehileng:Invar, FeNi36, Invar Standard, Vacodil36)
4J36 (Invar), eo hape e tsejoang ka kakaretso e le FeNi36 (64FeNi naheng ea US), ke motsoako oa tšepe oa nickel o hlokomelehang bakeng sa coefficient e tlase e ikhethang ea katoloso ea mocheso (CTE kapa α).
4J36 (Invar) e sebelisoa moo ho hlokahalang botsitso ba maemo a holimo, joalo ka lisebelisoa tse nepahetseng, lioache, litekanyo tsa seismic creep gauge, liforeimi tsa mask a moriti oa thelevishene, li-valve tsa li-motor, le lioache tsa antimagnetic. Ha ho etsoa tlhahlobo ea mobu, ha boemo ba boemo bo phahameng bo lokela ho etsoa, ho sebelisoa basebetsi ba Level (leveling rod) ho e-na le lehong, fiberglass kapa litšepe tse ling. Li-invar struts li ne li sebelisoa lipiston tse ling ho fokotsa katoloso ea tsona ea mocheso ka har'a lisilindara tsa tsona.
4J36 sebelisa oxyacetylene welding, motlakase arc welding, welding le mekhoa e meng. Kaha coefficient ea katoloso le metsoako ea lik'hemik'hale tsa motsoako e amana e lokela ho qojoa ka lebaka la tjheseletsa etsa hore phetoho motsoako motsoako, ho molemo ho sebelisa Argon arc tjheseletsa tjheseletsa filler tšepe ka ho khetheha e na le 0.5% ho 1.5% titanium, e le hore a fokotsa weld porosity le petsoha.
