Stainless Steel 17-4 PH Pipe Fittings are manufactured using a precipitation-hardened alloy comprised mainly of iron, 15–17.5% Chromium, 3–5% Nickel, 3–5% Copper, and minute quantities of Manganese, Silicon, and Carbon. Such fittings show great mechanical strength with tensile strength of up to 930 MPa and yield strength of 725 MPa in the H1025 condition. They further provide corrosion resistance of up to 38 HRC, along with strong hardness. 17-4 PH is highly suitable for applications involving high stress, corrosives, and precision-criticality due to the synergy of high strength, toughness, and weldability.
