Yes, Alloy C263 bars are recyclable. As a high-performance alloy, it can be melted and reused for manufacturing new products, making it an environmentally friendly material in the long term.
Alloy C263 rods are available in various sizes ranging from 1/8" to 6" in diameter, with lengths typically up to 12 feet. Common finishes include hot-rolled, cold-drawn, and polished.
Yes, Alloy C263 (also known as Hastelloy C263) can be welded using appropriate techniques such as TIG or MIG welding, with careful control of heat to avoid carbide precipitation.
Alloy C263 Bars and Rods find their place in extreme-temperature and high-stress environments, making them perfect for aerospace and turbine applications. You’ll often see them in combustion chambers, turbine casings, transition ducts, exhaust systems, fasteners, and hot-section engine parts. Their superior creep and oxidation resistance at elevated temperatures make them ideal for industrial gas turbines, high-temperature springs, petrochemical processing equipment, and thermal power plant components. Alloy C263 is also a go-to choice for precision-machined parts.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
