Chemical Composition Of Invar 36
Invar 36 physical properties:
1, Invar36 density, density: ρ = 8.1g / cm3.
2. Invar36 melting temperature range, melting temperature range: 1430 °C.
3, Invar36 Curie temperature, Curie temperature: 230 °C.

Invar 36 welding:
Invar 36 can be welded using all welding processes, including tungsten electrode welding, metal arc welding, plasma welding, argon arc welding, and manual arc welding. First consider pulsed arc welding. Before welding, the material should be in an annealed state, clean, free of oil, scratches, marking paint, etc. Low heat input must be used and the interlayer temperature should be below 120 °C. No pre-weld and post-weld heat treatment is required. Invar36 Recommended Soldering Materials If the weld bead performance is designed to be the same as the parent metal, an electrode of the same material as the parent metal is required. Welding wire: ERNiCr-3, welding rod: EniCrFe-3.
Invar 36 has the following features:
(1) It has an extremely low coefficient of thermal expansion between -250 ° C and +200 ° C.
(2) Good plasticity and toughness.
