EN 10088-3 X3CrNiCu18-9-4 is a high-alloy austenitic stainless steel grade with copper addition, designed for excellent corrosion resistance and moderate mechanical strength. The copper enhances resistance to acidic environments, particularly nitric acid, while the combination of chromium and nickel provides general corrosion resistance and good toughness. Supplied in bar form, X3CrNiCu18-9-4 stainless steel is suitable for chemical, marine, and industrial applications where reliable corrosion resistance is required. This grade conforms to the EN 10088-3 standard for stainless steel bars and rods. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of EN 10088-3 X3CrNiCu18-9-4 stainless steel bars. All materials are sourced from approved mills and supplied with consistent chemical composition, stable mechanical properties, and precise dimensional accuracy according to EN 10088-3 specifications. Forms of Supply: Round bar, hex bar, square bar, rectangular bar, flat bar, rod Explanation of Designation (X3CrNiCu18-9-4): • X – High-alloy steel • 3 – Approx. 0.03% carbon content • Cr18 – Approx. 18% chromium • Ni9 – Approx. 9% nickel • Cu4 – Approx. 4% copper for enhanced corrosion resistance Chemical Composition (% – typical limits): • Carbon (C): ≤ 0.05 • Chromium (Cr): 17.0 – 19.0 • Nickel (Ni): 8.0 – 10.0 • Copper (Cu): 3.5 – 4.5 • Silicon (Si): ≤ 1.00 • Manganese (Mn): ≤ 2.00 • Phosphorus (P): ≤ 0.045 • Sulphur (S): ≤ 0.015 Mechanical Properties (Typical, solution annealed): • Tensile Strength: 500 – 700 MPa • Yield Strength: ≥ 200 MPa • Elongation: ≥ 40% • Hardness: Typically ≤ 200 HB Key Features: • Austenitic stainless steel with copper addition • Excellent resistance to nitric acid and oxidizing environments • Good general corrosion resistance and toughness • Good weldability and formability • Stable mechanical properties in fabricated components • Non-magnetic in annealed condition Material Characteristics: EN 10088-3 X3CrNiCu18-9-4 stainless steel bar provides a reliable combination of corrosion resistance, mechanical stability, and workability.
