AMS 5643 GR. 17-4 PH Stainless Steel Seamless PIpe
Leave a message
If you are looking for seamless stainless steel tubing that combines high strength, corrosion resistance, and excellent wear resistance, we offer AMS 5643 GR. 17-4 PH Stainless Steel Seamless Pipe, designed for aerospace, energy, and demanding industrial applications.
17-4 PH is a precipitation-hardening martensitic-austenitic stainless steel with a typical chemical composition of 16–17.5% chromium (Cr), 3–5% copper (Cu), 3–5% nickel (Ni), and a small amount of niobium (Nb). After precipitation hardening treatment, it exhibits tensile strength up to 1100 MPa and excellent yield strength, while maintaining good corrosion resistance and toughness. This seamless pipe is resistant to high-temperature oxidation and stress corrosion cracking, making it suitable for high-temperature and high-pressure environments.
Our AMS 5643 17-4 PH seamless pipes are manufactured using advanced melting, forging, seamless pipe rolling, and solution treatment processes to ensure uniform wall thickness, precise dimensions, and a smooth surface. To guarantee product quality, we conduct chemical composition analysis, mechanical property testing, hardness and impact testing, and dimensional and surface defect inspection. We also provide Material Test Certificates (MTC), third-party inspection reports, and EN 10204 3.1 certificates to ensure reliable performance and data traceability for every pipe.


AMS 5643 GR. 17-4 PH seamless stainless steel pipes are widely used in aerospace engines, turbine shafts, precision mechanical components, marine engineering, and high-pressure pump and valve systems. With their high strength, corrosion resistance, wear resistance, and reliable dimensional stability, they provide long-term reliable piping and structural solutions for critical industrial projects.
