Understanding the Composition and Properties of Duplex X2CrNiMoN29-7-2 stainless steel

Duplex X2CrNiMoN29-7-2 stainless steel, as the name suggests, belongs to the family of duplex stainless steels. These steels are characterized by their dual-phase microstructure, comprising both austenite and ferrite phases. This unique combination endows them with a superior blend of properties compared to conventional austenitic or ferritic stainless steels. The specific designation “X2CrNiMoN29-7-2” provides insights into the alloy’s chemical composition. “X2” indicates a low carbon content (less than 0.02%), “Cr” signifies the presence of chromium, “Ni” denotes nickel, “Mo” represents molybdenum, and “N” indicates nitrogen. The numbers following these elements represent their approximate percentages in the alloy. This carefully balanced composition contributes to the exceptional properties of the steel, including high strength, excellent corrosion resistance, and good weldability. Our company understands the precise control required in the manufacturing process to achieve the optimal balance of these elements.

The high chromium content (around 29%) provides exceptional resistance to pitting and crevice corrosion, particularly in chloride-containing environments. Molybdenum further enhances corrosion resistance, while nickel stabilizes the austenite phase and improves ductility. Nitrogen acts as an austenite stabilizer and also increases strength. The combination of these elements results in a material that can withstand harsh conditions and maintain its structural integrity over extended periods. The mechanical properties of Duplex X2CrNiMoN29-7-2 stainless steel are equally impressive. It exhibits high tensile strength, yield strength, and elongation, making it suitable for demanding applications where both strength and ductility are crucial. Furthermore, its high resistance to stress corrosion cracking (SCC) makes it a preferred choice in environments where this phenomenon is a concern.
