1. What is the chemical composition of Inconel 738LC?
Answer:
Inconel 738LC is a nickel-based superalloy designed for high-temperature applications.
Typical composition: Ni ~55%, Cr ~18%, Co ~10%, Mo ~1%, Ti ~1%, Al ~0.5%, Nb ~3%, with trace amounts of Fe, C, B, and Zr.
The composition provides excellent creep, fatigue, and oxidation resistance at elevated temperatures.
2. What are the typical applications for Inconel 738LC coil/strip?
Answer:
Aerospace turbine blades, vanes, and combustion components.
Gas turbines and industrial high-temperature furnace parts.
Custom high-performance components where mechanical strength and oxidation resistance at 650–760°C are required.
3. What temperature range can Inconel 738LC operate in?
Answer:
Inconel 738LC maintains structural integrity up to ~760°C (1400°F).
It is designed for long-term service in high-stress, high-temperature environments, with excellent resistance to creep and thermal fatigue.
4. What forms and dimensions are available for customized Inconel 738LC products?
Answer:
Forms: Coils, strips, sheets, and custom profiles for OEM applications.
Thickness: Typically 0.5–10 mm (customizable).
Width: Up to 1000 mm or per customer specification.
Length: Coils or cut-to-length strips according to requirements.
Surface finish: Annealed, polished, or precision milled depending on application.
5. What quality assurance and testing are provided for Inconel 738LC?
Answer:
Chemical composition analysis (spectrometer tests) to ensure alloy standards.
Mechanical testing: Tensile strength, yield strength, hardness, and elongation.
Non-destructive testing (NDT): Ultrasonic, eddy current, or dye-penetrant inspection for defect-free coils/strips.
Heat treatment certification: Solution annealed or precipitation-hardened as per customer requirements.
Documentation: Mill test certificates (MTC), traceability, and inspection reports to comply with aerospace/industrial standards.
