Alloy 825 is a nickel based alloy that contains significant content of elements such as iron and chromium. Fittings produced from this alloy have been developed to provide exceptional resistance to numerous corrosive environments. The corrosion resistance property also takes into consideration both oxidation as well as reducing. The Alloy 825 Forged Reducing Tee has the ability to outperform many conventionally used stainless steel grades in corrosive environments particularly those environments that include sulphuric acid, sulphurous acid, phosphoric acid, nitric acid, hydrofluoric acid and organic acids as well as acidic chloride solutions. In addition to exhibiting superior corrosion resistance properties, the 825 Incoloy Half Coupling is also resistant to alkali compounds such as sodium hydroxide or potassium hydroxide.

UNS N08825 Threaded Union is another alloy that finds use in subsea applications on account of its outstanding performance in marine environments. Apart from being resistant to pitting and chloride stress related corrosion cracking, the Incoloy 825 Forged Fittings exhibit good formable and weldable characteristics. Just as forging improves several mechanical properties of the alloys, grade 825 fittings that have undergone a forging operation sees an improvement in ductility, fatigue resistance and impact resistance. The ASTM B564 specification which envelopes different requirements for nickel based alloy components such as fittings. The specification covers testing methods like tension test and nondestructive ultrasonic along with a chemical analysis. Moreover, the grain size along with the mechanical properties of the ASTM B564 Nickel 825 Socket Weld Elbow such as the tensile strength, yield strength, and elongation is to be measured.
