Located in the heart of Addis Ababa, Tariku Metals stands as a trusted partner for industrial progress, providing robust manufacturing solutions to Ethiopia’s growing sectors. We specialize in supplying high-grade Stainless Steel 17-4PH Forgings, a material chosen for its exceptional combination of strength and corrosion resistance. Our forgings are precisely engineered to meet the rigorous demands of critical applications, ensuring reliability and longevity for our clients’ most vital projects and contributing to the nation’s infrastructure and development.
This particular stainless steel is a precipitation-hardening alloy with a composition that includes chromium for corrosion resistance and nickel for toughness, balanced with additions of copper and niobium. Its true value lies in the exceptional mechanical properties gained through a specialized heat treatment, resulting in a material that offers very high strength and hardness, excellent resistance to stress corrosion cracking, and good toughness. This makes it significantly more durable than many standard stainless grades.

The ideal temperature range for forging Stainless Steel 17-4PH is 1850°F to 2050°F (1010°C to 1120°C). Post-forging, annealing or solution treating is necessary to achieve optimal properties.
Yes, Stainless Steel 17-4PH forgings can be forged into custom shapes. This alloy offers excellent strength, corrosion resistance, and machinability, making it suitable for precision custom forging applications.
The forging process for Stainless Steel 17-4PH typically takes several hours, including heating, shaping, and cooling. The exact duration depends on part size, complexity, and specific forging techniques used.
The unique properties of 17-4PH forgings make them indispensable in demanding environments. They are commonly used for essential components like turbine blades, pump shafts, and high-strength fasteners within the energy and water treatment sectors. In oil and gas, they serve in valve parts and fittings, while the automotive and aerospace industries rely on them for critical landing gear and engine parts. Essentially, anywhere you need a part that is strong, hard, and resistant to corrosion under stress, this material is an ideal choice.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
