Harsh Metalloys is a well-respected manufacturer and supplier of Stainless Steel 17-4 PH Pipes, located in Mumbai, India. These pipes are crafted from 17-4 PH stainless steel (UNS S17400), a precipitation-hardening martensitic alloy celebrated for its remarkable blend of high strength, hardness, and decent corrosion resistance. Designed for critical applications, Stainless Steel 17-4 PH Pipes deliver durability and outstanding mechanical properties, even in high-stress or mildly corrosive environments. Harsh Metalloys provides these pipes in a variety of sizes, schedules, and forms—both seamless and welded—catering to a wide range of industries, including aerospace, petrochemical, nuclear, and marine engineering.
Stainless Steel 17-4 PH Pipes consist of 17% chromium, 4% nickel, along with 3–5% copper and small amounts of niobium (columbium) to aid in precipitation hardening. These pipes can achieve tensile strength up to 1100 MPa, yield strength around 1000 MPa, and hardness up to 44 HRC, depending on the heat treatment (H900 to H1150). The alloy retains its mechanical strength at temperatures reaching 316°C and provides good resistance to oxidation and corrosion in mildly aggressive settings. Its excellent toughness, weldability, and dimensional stability make it a top choice for structural applications.
