Good Weldability Modern duplex grades have improved weldability with less risk of intermetallic phase formation, ensuring durable and defect-free joints. ✅ Resistance to Erosion Performs well in high-velocity or abrasive flow environments, reducing pipe wear and tear over time. ✅ Suitable for High-Pressure Systems The high mechanical strength supports usage in high-pressure pipelines and critical applications. ✅ Low Thermal Expansion Duplex steel has a lower thermal expansion coefficient compared to austenitic stainless steels, which helps in applications with temperature changes.
