With a strong commitment to excellence, George Metals supports a variety of industrial applications, providing products that align with international standards and meet customer specifications. Their expertise and cutting-edge manufacturing processes make them the go-to choice for clients looking for high-quality duplex steel bars and rods in a competitive market.
Duplex steel bars and rods feature a well-balanced microstructure of austenite and ferrite phases, typically comprising 20-25% austenite and 75-80% ferrite. This unique composition offers remarkable resistance to stress corrosion cracking and boasts high strength, often double that of standard stainless steels. Their mechanical properties include a tensile strength ranging from 620-880 MPa and impressive toughness even at low temperatures. The exceptional resistance to chloride-induced corrosion and fatigue makes them perfect for challenging environments that demand enhanced durability and performance.
