Brian Fasteners of Houston, USA, manufactures and provides Inconel 738 bars and rods through precision vacuum melting, hot working, and extended aging processes. The nickel superalloy was developed for high creep strength and resistance to oxidation in hot-section turbines. Each bar is subject to stringently dimensional and metallurgical quality inspection. Supplying aerospace, gas turbine, and thermal power industries, Brian Fasteners delivers custom bar lengths, fast delivery, and technical support. Being a reliable supplier, the company guarantees Inconel 738 bars meet critical performance specifications in severe high-temperature structure applications.
Inconel 738 contains 50–55% Ni, 19–22% Cr, 8–11% Co, ~2% Al+Ti, 0.15% C, and ~1.5% Hf. It has tensile strength of 1,000–1,600 MPa, yield strength 700–1,200 MPa, and elongation of 10–20%. Gamma-prime hardening with hafnium provides improved creep up to 850 °C and high oxidation resistance, suitable for ultra-hot-section durability.

Inconel 738 bars and rods are not typically used in cryogenic applications, as their properties are optimized for high-temperature environments. For cryogenic conditions, alloys specifically designed for low temperatures are preferred.
To choose the right Inconel 738 bars and rods, consider factors such as temperature requirements, corrosion resistance, mechanical strength, specific application needs, and compatibility with other materials in the operating environment.
Yes, Inconel 738 bars and rods should undergo regular inspection, especially in high-stress and high-temperature applications, to ensure they maintain their structural integrity and performance over time.
Brian Fasteners‘ Inconel 738 bars and rods are utilized in turbine blade platforms, rotor spacers, combustor liners, and diffuser supports for advanced aero and industrial gas turbines. They are preferred for hot-section hardware where resistance to oxidation and creep at extremely high temperatures is critical. Their mechanical stability and strength provide structural and rotating components handling extreme thermal cycles. Brian Fasteners provides Inconel 738 bars produced to strict standards, allowing reliable operation in critical hot-environment systems.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
