Ojas Pipes and Tubes stands out as a leading manufacturer and supplier of Hastelloy Seamless Pipes, proudly based in Kolkata, India. We’re recognized for providing top-notch piping solutions, offering a diverse selection of Hastelloy grades like C22, C276, B2, and X, all engineered to endure harsh chemical and high-temperature conditions. Our seamless pipes are crafted with cutting-edge technology and rigorous quality checks to comply with international standards such as ASTM B622. With remarkable corrosion resistance and mechanical strength, Ojas Hastelloy pipes are the go-to choice for industries like chemical processing, pharmaceuticals, marine, and nuclear power, especially for their most critical applications.
Hastelloy Seamless Pipes are mainly made up of Nickel (Ni: 50–60%), along with varying levels of Molybdenum (Mo: up to 16%), Chromium (Cr: up to 22%), Iron, Cobalt, and trace amounts of Carbon and Tungsten, depending on the specific grade. These alloys are known for their outstanding resistance to both oxidizing and reducing agents. Typical mechanical properties include a tensile strength ranging from 690 to 785 MPa, yield strength between 275 and 355 MPa, and elongation of 30 to 40%. Hastelloy’s remarkable toughness, weldability, and resistance to pitting, crevice corrosion, and stress corrosion cracking make it perfect for even the toughest service conditions.
