With an unwavering focus on quality, innovation, and customer satisfaction, the company makes sure every product meets high international standards. Their Inconel 690 Circles find extensive demand due to their high strength, corrosion resistance, and ability to withstand high temperatures, making them suitable for demanding industrial applications. Kunj caters to various industries such as petrochemicals, power generation, and shipping industries with stable and long-lasting solutions.
Inconel 690 Circles consist mainly of nickel (58–63%), chromium (27–31%), and iron, along with minor content of silicon, manganese, and carbon. This nickel-based, high-chromium alloy has excellent resistance to oxidation and corrosion at high temperatures. It has a tensile strength of approximately 380–620 MPa and yield strength of about 170–310 MPa, while showing good elongation (≥30%). The alloy demonstrates fine mechanical stability even under high temperatures. Its weldability and low thermal expansion make it well adapted to demanding applications that both demand strength and require corrosion resistance for long service life.
