1. What is Incoloy 800 and why is it used for spring wire?
Answer: Incoloy 800 is a nickel-iron-chromium alloy known for its excellent resistance to high temperatures and corrosion, particularly in oxidizing and reducing environments. It is used for spring wire because it maintains high tensile strength and elasticity even at elevated temperatures, making it ideal for industrial springs in furnaces, boilers, and chemical plants.
2. What are the available wire diameters?
Answer: The product comes in three standard diameters: 0.5 mm, 2 mm, and 3 mm. These sizes allow flexibility for different spring designs and applications, from delicate precision springs to heavy-duty industrial springs.
3. What temperature range can Incoloy 800 spring wire withstand?
Answer: Incoloy 800 wire can typically withstand continuous temperatures up to 700–800°C (1290–1470°F) and intermittent temperatures slightly higher. This makes it suitable for high-temperature industrial applications where conventional steel spring wires would fail.
4. How does the tensile strength of this spring wire compare to regular steel spring wire?
Answer: Incoloy 800 spring wire has higher tensile strength at elevated temperatures compared to ordinary carbon or stainless steel spring wire. This means it can store more energy per unit cross-section and retain its spring properties under heat without permanent deformation.
5. What industries typically use this high-temperature spring wire?
Answer: Industries include:
Power generation – for boiler and turbine springs.
Chemical processing – where corrosion and heat resistance are critical.
Aerospace – for high-temperature actuators and valves.
Automotive – in exhaust systems and turbochargers.
Industrial furnaces – for springs used in high-temperature mechanical assemblies.
