Based in Chennai, India, Kunj Sheets and Plates is a reputable producer and supplier of premium Inconel 718 coils and slitting coils that are designed to function in harsh conditions. Inconel 718, which is well-known for its exceptional strength, resistance to corrosion, and thermal stability, is perfect for demanding industries. For a range of industrial applications, Kunj provides these coils in bespoke sizes and finishes, guaranteeing accuracy and dependability. Kunj Sheets and Plates has a reputation for reliability, creativity, and outstanding product performance. It serves customers in the aerospace, marine, power generation, and chemical processing industries with its cutting-edge facilities and stringent quality control procedures.
Significant amounts of iron (balance), niobium (4.75–5.5%), molybdenum (2.8–3.3%), titanium, and aluminium are present in Inconel 718 Coil/Slitting Coil, a nickel-chromium alloy. Particularly in high-stress and high-temperature environments, this alloy provides exceptional strength and resistance to corrosion. In addition to having outstanding fatigue, creep, and rupture resistance, it has a tensile strength of about 1240 MPa and a yield strength of about 1035 MPa. The alloy is appropriate for intricate forming processes and welding without post-weld cracking because it maintains its toughness and ductility at cryogenic to high temperatures.
