Precision Alloy Nickel Iron Steel Invar 36 Nickel Bar Rod
1 . Description
36 alloy is a special ultra-low coefficient of heat expansion of low-iron-nickel alloy. One of carbon and manganese element of control is very important. Cold deformation can reduce the coefficient of thermal expansion, in particular within the framework of the heat treatment temperature coefficient of thermal expansion will enable stabilization. Has the following characteristics:
1.Has very low coefficient of heat expansion between the temperature of -250°C and 200°C.
2.Good toughness and plastic
Metallurgical structure
Invar 36 is the face centered cubic lattice structure
2 . Normal composition%
| Ni | 35~37.0 | Fe | Bal. | Co | - | Si | ≤0.3 |
| Mo | - | Cu | - | Cr | - | Mn | 0.2~0.6 |
| C | ≤0.05 | P | ≤0.02 | S | ≤0.02 |

3 . Typical Physical properties
| Density (g/cm3) | 8.1 |
| Electrical resistivity at 20℃(Ωmm2/m) | 0.78 |
| Temperature factor of resistivity(20℃~200℃)X10-6/℃ | 3.7~3.9 |
| Thermal conductivity, λ/ W/(m*℃) | 11 |
| Curie point Tc/ ℃ | 230 |
| Elastic Modulus, E/ Gpa | 144 |
4 . Heat treatment process
| Stress relief annealing | Heat to 530~550℃, keep for 1~2 h. Cool in the furnace |
| annealing | Heating to 830~880℃ ,keep holding for 30 min. Furnace cooling |
| Stabilization | (1) Heat to 830 ℃ in a protective atmosphere, hold for 20min. ~ 1h, quench (2)Temper |
| Precautions | (1) The alloy cannot be hardened by heat treatment |
| (2)Surface treatment can be sandblasted, polished and pickled |
