Neil Metals stands out as a leading manufacturer and supplier of Inconel Hollow Bars, proudly based in Kolkata, India. Known for their top-notch nickel alloy products, Neil Metals specializes in precision-engineered Inconel hollow bars that boast exceptional strength, heat resistance, and corrosion resistance. These bars are perfect for high-temperature and high-stress environments, making them ideal for industries like chemical processing, aerospace, marine, and power generation. With a commitment to advanced technology and rigorous quality control, Neil Metals guarantees that each product meets international standards. Their focus on performance, durability, and timely delivery has made them a trusted name in the specialty alloys market.
Inconel hollow bars are crafted from high-performance nickel-chromium-based alloys, mainly Inconel 600, 625, or 718. These alloys typically consist of about 58% nickel, 20–23% chromium, along with varying amounts of molybdenum, iron, and niobium depending on the specific grade. Inconel bars are known for their impressive mechanical strength, with tensile strength ranging from 750 MPa to over 1300 MPa, and they exhibit high creep resistance even at elevated temperatures. They maintain their structural integrity in extreme conditions and resist oxidation, carburization, and chloride-induced stress corrosion cracking. Plus, their hollow design helps reduce weight and material usage in certain structural or fluid-handling applications.
