Chuck Metals is a well-respected manufacturer and supplier based in Singapore, specifically on Pulau Ujong. They specialize in top-quality Incoloy Hollow Bars that are built to last, offering precision and outstanding performance even in tough industrial settings. Made from high-strength nickel–iron–chromium alloys, these hollow bars are designed to resist oxidation, carburization, and corrosive environments, even when the heat is on. Chuck Metals provides a variety of Incoloy Hollow Bars in different grades, sizes, and wall thicknesses to cater to a wide range of applications, all while adhering to international quality standards. Their products are a go-to choice in industries like petrochemical, marine, aerospace, and power generation, thanks to their unmatched reliability.
Incoloy Hollow Bars primarily consist of nickel (30–46%), chromium (19–24%), and iron, with carefully controlled amounts of titanium, aluminum, molybdenum, and other elements depending on the specific grade. They boast impressive mechanical properties, including a tensile strength ranging from 500 to 750 MPa, yield strength between 200 and 350 MPa, and good ductility. These alloys maintain their strength and resist scaling, even when exposed to high temperatures and harsh chemical environments for extended periods.

Yes, Incoloy Hollow Bars can be welded using appropriate techniques, such as gas tungsten arc welding (GTAW). Proper welding procedures ensure strong, durable joints with minimal risk of cracking or corrosion.
Incoloy Hollow Bars are highly resistant to corrosion due to their alloy composition, and typically do not require additional coatings. However, in extremely aggressive environments, further protective measures may be considered for enhanced durability.
These hollow bars find extensive use in heat exchangers, condensers, marine hardware, pollution control systems, and furnace components. Their ability to resist corrosion in acidic, alkaline, and saline conditions makes them perfect for offshore structures, chemical processing plants, and desalination units. Incoloy Hollow Bars are also highly valued in power plants, aerospace applications, and refinery equipment, where strength, thermal stability, and a long service life are essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
