17-4 PH Stainless Steel Pipe (UNS S17400)
Lork Group is a leading supplier and exporter of 17-4 PH pipes and tubes. 17-4 PH is a martensitic precipitation-hardening stainless steel with additions of copper (Cu), niobium (Nb), and tantalum (Ta). The grade combines high strength and hardness values with moderate corrosion resistance. Different heat treatment temperatures can optimize mechanical properties, e.g., yield strength at 1100 – 1300MPa.
17-4PH pipe has good fabricating characteristics and can be age-hardened by a single-step, low-temperature treatment. Is a versatile material widely used in the aerospace, chemical, petrochemical, food processing, paper, and general metalworking industries.
