Duplex steel mechanical tubing is crafted from duplex stainless steel, which features a balanced microstructure of austenitic and ferritic stainless steels. This unique blend offers outstanding corrosion resistance, particularly against pitting, crevice corrosion, and stress corrosion cracking in environments rich in chlorides. Additionally, it boasts high tensile and yield strength, impressive toughness, and reliable weldability. With excellent dimensional accuracy, consistent wall thickness, and smooth internal surfaces, this tubing is designed for durability and dependable performance in applications that demand both mechanical strength and resistance to harsh operating conditions.
