ASTM F1684 Invar 36 Bar
Introduction
ASTM F1684 Invar 36 is a nickel-iron, low-expansion alloy containing 36% nickel. It maintains nearly constant dimensions over the range of normal atmospheric temperatures and has a low coefficient of expansion from cryogenic temperatures to about 500°F. The alloy also retains good strength and toughness at cryogenic temperatures.
ASTM F1684 is a standard Specification for Iron-Nickel and Iron-Nickel-Cobalt Alloys for Low Thermal Expansion Applications.
ASTM F1684 Invar 36 Bar with a rate of thermal expansion approximately one-tenth that of carbon steel at temperatures up to 400°F (204°C). This alloy is used for applications where dimensional changes due to temperature variation must be minimized or in conjunction with high expansion alloys in applications where a motion is desired when the temperature changes.

Invar 36 Bar Selection Recommendations
1. Based on Lork Group's inventory of ASTM F1684 and commonly used specifications, Invar 36 bars are typically available in the following forms:
Shapes: Round bars, square bars, hexagonal bars.
2. Select according to the supply status of the production execution standard:
- Hot rolled/forged: Suitable for rough-machined parts with low requirements for surface finish and tolerances.
- Cold drawn/finish drawn: High dimensional accuracy, good surface finish, suitable for precision machining.
- Annealed state: Softer material, easy to perform complex machining.
- Solution treated state: To obtain optimal low expansion properties and uniform microstructure.
