Emilio Stainless, a trusted manufacturer and supplier based in Manila, Philippines, offers high-performance Stainless Steel 17-4 PH Tubing designed to meet the demanding needs of modern industries. Known for its outstanding combination of strength, hardness, and corrosion resistance, this tubing is ideal for applications requiring durability under high stress and pressure. Emilio Stainless ensures every tube is precisely engineered and tested to international standards. With excellent weldability and toughness, 17-4 PH Tubing delivers reliable performance in both mechanical and structural uses, making it a preferred choice for industrial, marine, and aerospace applications.
Stainless Steel 17-4 PH Tubing is composed of approximately 17% chromium, 4% nickel, 3–5% copper, and small additions of niobium for precipitation hardening. This chemical makeup offers high tensile strength, with values reaching up to 1000–1200 MPa, and excellent resistance to corrosion and oxidation. It also retains good toughness and dimensional stability even after heat treatment. The tubing provides superior mechanical properties, allowing it to perform effectively in high-pressure and high-temperature environments where both strength and reliability are essential.
