CD4MCU Duplex Stainless Steel Round Bar

Product Overview

CD4MCU is a high-performance duplex (ferritic-austenitic) stainless steel round bar offering exceptional corrosion resistance, high strength, and excellent wear resistance. Its unique composition, including chromium (Cr), molybdenum (Mo), and copper (Cu), makes it ideal for harsh environments such as seawater, chemical processing, and oil & gas applications.

Key Features & Benefits

✔ Superior Corrosion Resistance – Resists pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-rich and acidic environments.
✔ High Strength & Toughness – Nearly double the yield strength of standard 300-series stainless steels (e.g., 316L).
✔ Excellent Wear & Erosion Resistance – Ideal for abrasive and high-flow conditions.
✔ Good Weldability & Fabrication Properties – Requires controlled welding techniques for optimal performance.
✔ Cost-Effective Solution – Longer service life reduces maintenance and replacement costs.
