Neil Metals, based in Kolkata, India, has built a solid reputation as a top-notch manufacturer and supplier of high-quality Hastelloy Hollow Bars. With a focus on corrosion-resistant alloys, they provide an impressive selection of Hastelloy grades, including C22, C276, and X, all tailored for the toughest industrial conditions. Their hollow bars are crafted with precision and meet international standards like ASTM and ASME. Renowned for their remarkable strength, machinability, and resistance to chemicals, these bars play a crucial role in various industries. Neil Metals is dedicated to delivering quality products on time and ensuring customer satisfaction, serving sectors such as chemical processing, power generation, marine, and aerospace.
Hastelloy Hollow Bars are primarily made up of nickel (up to 60%) and molybdenum (up to 16%), with varying amounts of chromium, iron, cobalt, and tungsten depending on the specific grade. This unique composition grants them exceptional corrosion resistance, particularly in harsh chemical environments. On the mechanical side, Hastelloy bars boast a tensile strength ranging from 690 to 785 MPa, yield strength between 283 and 355 MPa, and an elongation of about 40 to 45%. These characteristics remain stable even under high stress and temperature, making Hastelloy Hollow Bars perfect for applications that require structural integrity, durability, and resistance to corrosion in demanding industrial settings.

These bars are extensively utilized in industries that demand outstanding corrosion resistance and mechanical performance. In the chemical and petrochemical sectors, they find their place in reactors, heat exchangers, and piping systems that come into contact with strong acids and oxidizing agents. In the marine industry, they stand up to saltwater corrosion in pump shafts, structural supports, and valves. Power generation facilities rely on them for boiler components, condensers, and flue gas scrubbers. In aerospace, they are used for high-temperature fasteners and engine parts. Their ability to resist localized corrosion also makes them a great fit for the pharmaceutical, waste treatment, and paper pulp processing industries.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
