Harsh Metalloys stands out as a top manufacturer and supplier of Stainless Steel 17-7 PH Pipes, with its base in Mumbai, India. Crafted from a robust, precipitation-hardening stainless steel alloy (UNS S17700), these pipes boast an impressive mix of high tensile strength, good formability, and resistance to corrosion. They’re perfect for situations where a strong yet lightweight material is crucial, along with fatigue resistance and dimensional stability. Harsh Metalloys offers these pipes in a variety of sizes and finishes, including seamless and welded options, designed to meet the needs of demanding sectors like aerospace, chemical processing, marine, and automotive engineering.
Stainless Steel 17-7 PH Pipes are mainly made up of 17% chromium, 7% nickel, and trace amounts of aluminum, which allows for effective precipitation hardening. This alloy achieves a tensile strength of up to 1380 MPa and a yield strength of at least 1170 MPa, along with impressive hardness and fatigue resistance, particularly when heat-treated (CH900, RH950, or TH1050). It maintains its strength and stability even at high temperatures and during cyclic loading. Its corrosion resistance is comparable to that of 304 stainless steel, but with improved mechanical properties, making it an excellent choice for structural and dynamic-load applications in mildly corrosive environments.
