Ayten Tube Fittings is a well-respected manufacturer and supplier located in Addis Ababa, Ethiopia, specializing in top-notch Stainless Steel 321 Ball Valves. The company has built a solid reputation for its precision engineering, outstanding product performance, and unwavering commitment to international quality standards. Ayten Tube Fittings offers durable, corrosion-resistant ball valves that are designed for reliable shutoff and flow control, even in tough industrial settings. With a strong emphasis on customer satisfaction, innovation, and long-lasting reliability, Ayten Tube Fittings proudly serves a variety of industries throughout Ethiopia and beyond with high-quality stainless steel valve solutions.
The Stainless Steel 321 Ball Valves are crafted from stabilized austenitic stainless steel, which includes iron, chromium (17–19%), nickel (9–12%), and titanium (up to 0.7%). The addition of titanium helps stabilize the alloy, preventing carbide precipitation and boosting resistance to intergranular corrosion. These valves boast impressive mechanical properties, featuring a tensile strength of around 515 MPa and a yield strength close to 205 MPa. They also provide exceptional resistance to oxidation, maintain high-temperature stability, and exhibit superior toughness, ensuring dependable operation and longevity in demanding industrial conditions.
