Nguyen Fittings and Plates is a well-known supplier of Alloy 20 Forged Fittings. These fittings are perfect for acidic and corrosive environments, especially those involving sulfuric acid. Made according to ASTM B564 and ASME B16.11 standards, our forged fittings (socket weld and threaded) resist pitting, chloride stress corrosion, and acid attack. Alloy 20 is a nickel-iron-chromium superalloy that offers a balance between the performance of stainless steel and high-nickel alloys. We precision-engineer our fittings for use in chemical, petrochemical, pharmaceutical, and power generation industries where material stability and resistance to corrosion are crucial.

Alloy 20 contains nickel (about 32–38%), chromium (19–21%), iron (the remainder), along with copper (3–4%), molybdenum (around 2%), and niobium for stabilization. It provides a tensile strength of 550–620 MPa and a yield strength of 240 MPa, along with excellent resistance to sulfuric acid and chloride corrosion. It preserves its mechanical integrity in both normal and high-temperature settings. These fittings are also easy to weld, form, and maintain precise dimensions, which makes them suitable for harsh media.
