Nestled in the heart of Kuala Lumpur, Malaysia, Maria Pipes and Tubes stands out as a leading manufacturer and supplier of Duplex Steel Tubing S32205. Our tubing is renowned for its exceptional strength and impressive corrosion resistance, making it perfect for tough applications. As a trusted name in the industry, we deliver precision-engineered tubing that adheres to international standards like ASTM A789 and ASTM A790. The Duplex S32205 tubing boasts remarkable mechanical properties and outstanding resistance to stress corrosion, making it a go-to choice for the oil & gas, petrochemical, marine, and power generation sectors. With cutting-edge manufacturing and rigorous quality control, we ensure our tubing performs reliably in both local and global markets.
Duplex Steel S32205 tubing is made up of about 22% chromium (Cr), 5–6.5% nickel (Ni), 3–3.5% molybdenum (Mo), and the rest is iron (Fe), along with trace amounts of nitrogen (N), manganese (Mn), and silicon (Si). This unique dual-phase alloy features a well-balanced austenitic-ferritic microstructure, which significantly boosts its resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. The carefully crafted chemical composition delivers a blend of strength and corrosion resistance that outshines standard austenitic stainless steels, making S32205 perfect for challenging environments with seawater, acidic fluids, and high chloride exposure.
