Harsh Flanges is a premier manufacturer and distributor of high-quality Inconel 625 flanges, known for their exceptional durability and resistance to extreme temperatures, corrosion, and pressure. With years of industry expertise, Harsh Flanges delivers precision-engineered solutions tailored to meet the demands of aerospace, marine, chemical processing, and oil & gas industries. Our Inconel 625 flanges are crafted from top-grade nickel-chromium alloy, ensuring superior performance in harsh environments. Committed to excellence and innovation, Harsh Flanges sets the standard for reliable, high-performance flanges that support critical operations across diverse industrial sectors.
Inconel 625 flanges are composed primarily of nickel (58% minimum), chromium, molybdenum, and niobium, with trace elements that enhance durability. They exhibit excellent mechanical properties, including high tensile strength, a yield strength around 448 MPa, and impressive elongation. Known for superior resistance to oxidation, corrosion, and stress cracking, Inconel 625 flanges perform well in extreme temperatures and corrosive environments. Their advantages include long-lasting reliability in harsh conditions, making them ideal for applications in aerospace, chemical processing, and marine industries where strength and durability are essential.
Nickel (58% min), chromium (20–23%), molybdenum (8–10%), and niobium (3.15–4.15%) make up the majority of Inconel 625 Flanges, with trace amounts of iron, cobalt, and manganese. Superior resistance to oxidation, pitting, and stress corrosion cracking is provided by this alloy. Mechanical characteristics include a minimum elongation of 30%, a yield strength of 414 MPa, and a tensile strength of about 827 MPa. Inconel 625 flanges are perfect for harsh and high-stress situations because of their exceptional fatigue strength, weldability, and ability to maintain their integrity at temperatures as high as 980°C.

Industries that demand exceptional corrosion resistance and mechanical strength in harsh environments make extensive use of Inconel 625 flanges. They are perfect for use in nuclear reactors, offshore oil and gas platforms, marine systems, chemical processing equipment, and aerospace components. These flanges are frequently used to join pumps, valves, and pipes in systems that are subjected to harsh chemicals, seawater, and high temperatures. They are vital for maintaining the durability and security of vital infrastructure because of their resistance to oxidation, stress-corrosion cracking, and crevice corrosion, particularly in settings with high pressure, heat, or corrosive materials.
