Harsh Metalloys is a leading producer and supplier of Stainless Steel 17-4 PH Tubings, based in Mumbai, India. We offer high-quality tube solutions designed for use in applications demanding superior strength, hardness, and moderate to good resistance to corrosion. Our 17-4 PH tubings are produced from precipitation-hardening stainless steel and provide excellent mechanical properties and dimensional stability. Our tubes are made with state-of-the-art technologies and rigorous quality control to satisfy international standards. Harsh Metalloys is committed to providing long-lasting, precision-engineered products with timely delivery and best prices to cater to a diverse group of industrial customers both within India and worldwide.
Stainless Steel 17-4 PH Tubings consist of 15–17.5% chromium, 3–5% nickel, 3–5% copper, and minor amounts of niobium, manganese, silicon, and carbon. These tubings are strengthened by precipitation hardening following heat treatment and may possess tensile strength of as much as 1100 MPa and yield strength of about 1000 MPa. With a maximum hardness of 44 HRC (in H900 condition), 17-4 PH tubings provide high wear resistance, fatigue strength, and satisfactory corrosion resistance, particularly in moderately corrosive conditions. They preserve mechanical strength up to 600°F (315°C), which renders them suitable for high-performance engineering work.
