Elvis Nickel Alloys stands out as a trusted manufacturer and supplier of Inconel 825 Tube Fittings right here in Houston, USA. We pride ourselves on delivering top-notch fittings designed for high-performance and corrosion-sensitive applications. Inconel 825 is a unique nickel-iron-chromium alloy, enhanced with molybdenum, copper, and titanium, which grants it exceptional resistance to corrosion, stress cracking, and both oxidizing and reducing environments. Our tube fittings are crafted with precision to meet global standards, including ASTM B564. Commonly found in chemical processing, offshore oil and gas, acid production, and pollution control systems, these fittings guarantee leak-proof, long-lasting performance even in extreme pressure and temperature situations.
Inconel 825 tube fittings are made up of about 42% nickel, 21.5% iron, and 20–23.5% chromium, along with molybdenum (~3%), copper (~2%), and titanium (~1.2%). This distinctive blend provides remarkable resistance to sulfuric and phosphoric acids, as well as protection against pitting, stress-corrosion cracking, and intergranular corrosion. With a tensile strength ranging from 550 to 700 MPa, Inconel 825 maintains impressive mechanical properties even at elevated temperatures of up to 540°C (1000°F). These tube fittings also exhibit stability in both oxidizing and reducing atmospheres, making them a reliable choice for handling critical and corrosive process media.
