Invar 36 Plate Annealed FAQs

Q1: What are the key material properties of Invar 36 Plate Annealed?

A1: Invar 36 Plate Annealed is primarily composed of 36% nickel with the balance mostly iron, which gives it an exceptionally low coefficient of thermal expansion (around 1.2 × 10⁻⁶ K⁻¹ at 20°C). This stability extends over a broad temperature range, making it ideal for high-precision applications. It also exhibits good toughness, moderate tensile strength, and excellent dimensional stability, even under thermal cycling conditions.

Q2: How can this Invar 36 Plate Annealed be processed or fabricated?

A2: Invar 36 Plate Annealed can be machined using standard techniques, although its low thermal conductivity necessitates adjusted speeds and feeds. It can be welded using methods like TIG and MIG, but preheating and post-weld stress relief help maintain dimensional stability. Cold working and forming are feasible; however, subsequent annealing may be required to restore the alloy’s low-expansion characteristics and eliminate stress-induced distortions.

Q3: Which quality standards and certifications apply to Invar 36 Plate Annealed?

A3: Commonly, Invar 36 Plate Annealed is produced to ASTM F1684 or related specifications, ensuring strict compositional and mechanical property requirements. Manufacturers may also certify compliance with ISO 9001 for quality management and AS9100 for aerospace applications. Additional certifications, such as AMS or customer-specified standards, may apply depending on end-use requirements, underscoring the importance of traceable production processes and rigorous inspection protocols.
