The Stainless Steel 347 and 347H ERW Pipes are crafted from titanium-stabilized austenitic stainless steel, which includes chromium, nickel, and titanium. The 347H variant stands out with its higher carbon content, providing enhanced strength at high temperatures and better creep resistance. Both grades excel in resisting intergranular corrosion, pitting, and oxidation, even in harsh environments. On the mechanical side, these pipes offer high tensile and yield strength, toughness, and fatigue resistance, all while ensuring good weldability and machinability. Their ERW construction guarantees uniform wall thickness, dimensional stability, and reliable performance under high-pressure and high-temperature conditions.
