Salem Stainless Steel Suppliers Pvt. Ltd. is a trusted supplier of premium-quality Stainless Steel Duplex Angles, engineered to deliver exceptional strength and corrosion resistance for demanding industrial environments. Combining the best properties of austenitic and ferritic stainless steels, SS Duplex Angles offer an ideal balance of durability, performance, and cost efficiency.
Duplex angles are so named because they possess a dual-phase microstructure. They are engineered to consist of approximately 50% austenite and 50% ferrite. This balanced chemistry allows the material to inherit the best properties of both families: the corrosion resistance of the 300-series and the high strength of the 400-series. These angles are widely used in industries where reliability and performance under harsh conditions are critical.
