630 Stainless Steel Seamless Pipe (17-4PH / UNS S17400, 1.4542, GB 05Cr17Ni4Cu4Nb) 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
