Victor Sheets and Plates, a premier manufacturer and supplier headquartered in Abuja, Nigeria, pioneers excellence in advanced alloy solutions with its superior Stainless Steel 17-7 PH Angles. Engineered through precision metallurgy, these precipitation-hardened angles deliver exceptional strength, resilience, and corrosion resistance. Built for applications where both mechanical endurance and dimensional stability are paramount, 17-7 PH Angles represent the perfect fusion of innovation and integrity. At Victor Sheets and Plates, each angle embodies unwavering performance, reliability, and craftsmanship—making them indispensable in industries where structural strength and lasting performance define success.
The Stainless Steel 17-7 PH Angle is a semi-austenitic precipitation-hardening alloy composed of 16–18% chromium, 6.5–7.75% nickel, and small additions of aluminum (0.75–1.5%) for enhanced hardenability. It achieves superior mechanical properties through controlled heat treatment, providing a tensile strength of up to 1310 MPa with excellent fatigue and creep resistance. The alloy exhibits remarkable corrosion resistance comparable to 304 stainless steel, while maintaining outstanding toughness and stability at elevated temperatures—ensuring long-term reliability under severe mechanical and environmental stress.
