Brian Fasteners in Houston, USA, offers high-grade Haynes HR-120 Bars and Rods, built for extended exposure to high-temperature industrial conditions. This solid solution-strengthened alloy is known for its excellent oxidation and resistance to carburization up to 1150°C. The bars from Brian Fasteners are precision-finished and customized to client specifications, making them ideal for use in heat treating equipment, petrochemical furnaces, and reformer tubes. With outstanding weldability and workability, Haynes HR-120 bars are suitable for difficult thermal cycling environments, providing superior service life and consistent mechanical performance.
Haynes HR-120 contains about 37% Fe, 30% Ni, 25% Cr, 2% Mn, and minor amounts of Si, N, and rare earths. It offers tensile strength around 700–750 MPa, yield strength of approximately 320 MPa, and elongation of about 40%. HR-120 shows high resistance to carburization, sulfidation, and oxidation at elevated temperatures, and retains strength up to 1150°C. It maintains a stable microstructure under thermal cycling and resists grain coarsening, making it suitable for heat-exposed structural applications.
The most common diameters for Haynes HR-120 rods typically range from 6 mm (0.25 inch) to 50 mm (2 inches), depending on the application and manufacturer specifications.
Haynes HR-120 rods are typically available in diameters ranging from 3 mm (0.12 inches) to 100 mm (3.94 inches), catering to various industrial applications. Custom sizes may also be available.
To maintain HR-120 bars, regularly clean them with a mild detergent, avoid corrosive environments, inspect for damage, apply anti-corrosion coatings if needed, and store in a dry, controlled environment.
Haynes HR-120 bars are used in radiant tubes, heat-treating furnace parts, ethylene pyrolysis coils, and recuperators. Its high-temperature strength and oxidation resistance make it ideal for petrochemical and metallurgical processes involving aggressive atmospheres. HR-120 performs well in environments where carburization and thermal fatigue are concerns. Brian Fasteners supplies customized HR-120 rods and bars to ensure durable performance under intense industrial heat exposure, contributing to reduced downtime and longer component life.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
