From the heart of Hamilton, New Zealand, Blundell Pipes and Tubes has built a strong reputation for supplying top-tier industrial materials. We take particular pride in our Duplex Steel Pipes S31803, a product engineered to meet the toughest challenges. Known for their exceptional strength and excellent corrosion resistance, these pipes are a reliable choice for engineers and project managers who demand durability and longevity from their critical infrastructure components, backed by the trusted quality of a local manufacturer.
The strength of Duplex Steel S31803 comes from its balanced composition of chromium, nickel, molybdenum, and nitrogen. This unique blend gives it a mixed microstructure that delivers the best of both worlds: the high strength of ferritic steels and the superior corrosion resistance of austenitic grades. The result is a material with outstanding mechanical properties, including high resistance to stress corrosion cracking and double the yield strength of standard stainless steels, making it both tough and resilient.
