1. What makes Inconel 625 sheet/plate suitable for high-strength applications?
Answer:
Inconel 625 is a nickel-chromium-molybdenum alloy with excellent precipitation-hardening and solid-solution strengthening.
It maintains high tensile, yield, and creep strength even at temperatures up to 980°C (1,800°F).
Its fatigue resistance and toughness make it ideal for structural and high-pressure applications.
2. What industries commonly use Inconel 625 sheets and plates?
Answer:
Aerospace: turbine casings, combustor liners, fasteners
Chemical & Petrochemical: heat exchangers, reactor vessels, pipe linings
Marine: seawater pumps, valves, desalination equipment
Energy & Power: gas turbines, boiler components, superheaters
Other Industrial Applications: any high-temperature or corrosive environment requiring both strength and corrosion resistance
3. What testing is done to ensure the quality of Inconel 625 sheet/plate?
Answer:
Chemical composition verification (PMI or spectrometer analysis)
Mechanical testing: tensile, yield, elongation, and hardness
Non-destructive testing (NDT): ultrasonic, eddy current, or dye penetrant inspection
Dimensional and surface inspection: thickness, width, length, straightness, surface finish
Certification: Mill Test Certificates (MTC) per ASTM / AMS standards
4. What customization options are available for Inconel 625 sheets and plates?
Answer:
Thickness and size: can be tailored to project drawings
Surface finish: bright, polished, 2B, or BA
Heat treatment: solution annealing, stress-relieving, or aging
Edge preparation: square, beveled, or machined
Packaging: factory-direct, individually wrapped, or palletized for shipment
5. How should customers specify Inconel 625 sheet/plate for procurement?
Answer:
Provide material grade: Inconel 625 (ASTM B444 / AMS 5662)
Specify thickness, width, length, and surface finish
Indicate mechanical property or heat treatment requirements
Include any certification requirements (MTC, ASME, ISO, EN)
Clarify application conditions (temperature, corrosion media) to ensure optimal performance
