Kyoga Flanges, based in Bedok, Singapore, is a trusted manufacturer and supplier of Incoloy 825 Flanges, engineered for demanding industrial applications that require excellent corrosion resistance and high strength. Made from premium Incoloy 825, a nickel-iron-chromium alloy with molybdenum and copper, these flanges provide superior resistance to pitting, stress corrosion cracking, and oxidizing/reducing environments. Designed for durability and leak-proof connections, Kyoga’s Incoloy 825 flanges are ideal for chemical processing, oil and gas, seawater, and offshore industries where operational reliability, long-term performance, and safety are critical.
Incoloy 825 flanges consist mainly of nickel (38-46%), steel and chromium, to which molybdenum, copper and titanium are added to improve their performance. This alloy offers excellent resistance to pitting, stress corrosion cracking and oxidation. Mechanically, Incoloy 825 possesses a tensile strength of around 550 MPa and a yield strength of around 220 MPa, with an expansion of around 30% The flanges maintain stability and strength at elevated temperatures. Benefits are good resistance to environmental corrosion, acidity and seawater, which makes it suitable for chemical processing, oil and gas, and marine spatial uses which is critical for reliability

Incoloy 825 flanges find extensive use in situations where there is a need for high corrosion resistance and high temperatures. They are best suited for the petroleum and chemical industries, where phosphoric and sulfuric acids are well managed. In the oil and gas industry applications, these flanges find application in pipelines because of their stress resistance, corrosion and cracking resistance in offshore acid and gas conditions besides their efficiency in mechanical fouling, heat exchangers, nuclear fuel reprocessing and marine engineering. Their turbulence resistance in environments guarantees reliability and durability even in extreme operating conditions.
