Scorodite Stainless India Private Limited offers premium quality Alloy 20 Tubes, engineered for high performance in harsh chemical environments. Designed to resist corrosion, especially in sulfuric acid and chloride stress environments, Alloy 20 tubing is a go-to solution in critical industrial applications. Manufactured with precise control, these tubes meet international specifications, ensuring reliability and strength under pressure.

What exactly are Alloy 20 Tubes? Made from a nickel-iron-chromium alloy with additions of copper and molybdenum, Alloy 20 is known for its excellent corrosion resistance, particularly in sulfuric acid applications. These tubes are fabricated using advanced welding methods, followed by heat treatment and testing to ensure consistent mechanical and metallurgical properties. The chemical composition, which includes a blend of nickel (32-38%), chromium (19-21%), molybdenum (2-3%), and copper (3-4%), gives the material excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
