Duplex steel gets its remarkable strength from a balanced composition of chromium, nickel, molybdenum, and nitrogen. This unique blend gives these pipes exceptional resistance to corrosion and stress cracking, far surpassing common stainless steels. Their mechanical properties are impressive, offering high tensile and yield strength, which allows for thinner pipe walls and reduced weight without sacrificing any of the performance, making them both efficient and incredibly durable.
