From Hamilton, New Zealand, Neesham Flanges stands as a trusted source for robust industrial components, specializing in the supply of Stainless Steel 17-4 PH Flanges. We understand that in demanding environments, reliability is non-negotiable. That’s why we focus on providing flanges made from this exceptional precipitation-hardening steel, known for its remarkable strength and corrosion resistance. Our commitment is to deliver components that not only meet but exceed the rigorous demands of local and international industries, ensuring your systems are built with durability and performance in mind.
The composition of 17-4 PH stainless steel is a careful balance, primarily built around chromium and nickel, but its defining characteristic is the addition of copper and niobium. This specific chemical recipe allows it to undergo a heat treatment process called precipitation hardening. This process transforms its mechanical properties, granting it a strength level that rivals many high-strength steels while maintaining the corrosion resistance expected from stainless steel. The result is a material that offers an outstanding combination of toughness, good fatigue resistance, and the ability to perform reliably under stress.
