Inconel 718 Flanges

Inconel 718 Flanges are strong and reliable pipe fittings made from a nickel-chromium superalloy. This alloy is well known for its ability to handle extreme heat, corrosion and fatigue. With a density of 8.1 g/cm³ and a melting point of 1350 °C, it delivers outstanding mechanical strength. The material has an elongation of 45%, a yield strength of 70,000 psi and a tensile strength of up to 135,000 psi. Metracore Alloys is a reputable manufacturer and supplier of Inconel 718 flanges offering strong goods that are made following international standards.

These flanges satisfy ANSI, DIN, JIS, BS and other international dimensions in accordance with ASTM B564 / ASME SB564. The sizes that are available are ½” NB to 12″ NB, and the pressure ratings range from 150 LBS to 2500 LBS. Face types include Ring Type Joint (RTJ), Raised Face (RF) and Flat Face (FF). High strength, extended service life, resistance to corrosion and age hardening capacity are important characteristics. They are appropriate for demanding applications because they function well at temperatures as high as 1300°F (704°C). Benefits include cost effectiveness, ease of installation, low maintenance and dependability in challenging circumstances.

Inconel 718 Flanges are used in many industries. They are important for space components, rocket motors and turbines in aerospace. They can tolerate high pressure and corrosive fluids in wellheads and pipelines for gas and oil. For safe, effective operation, power plants use them in turbines and boilers. Because of their resistance to harsh chemicals they are also frequently used in heat exchangers, reactors and chemical processing. They are also essential to the marine and nuclear industries due to their strength, durability, and weldability. Careful raw material selection, melting, forging, machining, heat treatment and aging procedures to increase strength are all part of the manufacturing process.

Inconel 718 Pipe Flanges, ASTM B564 Inconel 718 Flanges, Alloy 718 Flanges

Every flange undergoes strict quality checks, including PMI, ultrasonic, radiographic, and mechanical testing. ASTM/ASME B564 and UNS N07718 standards are met by the products.
