Product Description 630 seamless pipe, also known as 17-4PH, is a martensitic precipitation hardening stainless steel seamless tube. It contains copper and niobium elements. After solution treatment and aging heat treatment, fine copper-rich precipitates form inside the matrix to achieve ultra-high strength, hardness and moderate corrosion resistance. It is magnetic, with corrosion resistance close to 304 stainless steel, and mechanical properties can be adjusted by different aging heat treatment processes (H900, H1025, H1150 etc.).
Chemical Composition (wt%, max, balance Fe) C ≤0.07, Mn ≤1.00, Si ≤1.00, P ≤0.040, S ≤0.030, Cr 15.50–17.50, Ni 3.00–5.00, Cu 3.00–5.00, Nb+Ta 0.15–0.45
Mechanical Properties (H900 aging condition, reference)
Note: Properties change with different aging treatments. H1150 delivers lower strength but better toughness and stress corrosion resistance.
Specifications Outer Diameter: 4mm ~ 300mm Wall Thickness: 0.5mm ~ 50mm Standards: ASTM A564, ASTM A213, EN 10216 Surface: Pickled, polished, bright finish
Features
Applications Oil & gas pipeline components, high-pressure valve bodies, pump sleeves, aerospace structural tubing, marine corrosion-resistant parts, paper mill equipment, food machinery, chemical equipment, high-load mechanical parts, nuclear auxiliary components.
