Stainless Steel 17-4 PH Pipe Fittings are precipitation-hardening stainless steels composed of approximately 15–17.5% chromium, 3–5% nickel, and 3–5% copper, with added niobium for controlled hardening. This unique chemistry allows the material to achieve remarkable tensile and yield strength after heat treatment while maintaining good toughness. The fittings display excellent resistance to corrosion, stress cracking, and fatigue. Their strong mechanical properties—high hardness, stability, and load-bearing capacity—make them ideal for applications requiring superior strength and long-term reliability under varying temperatures and pressures.
