Sadiki Metals, located in Kinshasa, Congo, has built a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel products, including Stainless Steel 15-5 PH Hex Bars and Rods. These hex bars and rods are celebrated for their remarkable strength, resistance to corrosion, and impressive hardness, making them perfect for tough industrial and aerospace applications. The Stainless Steel 15-5 PH is a precipitation-hardening martensitic stainless steel that showcases outstanding mechanical properties once heat-treated. At Sadiki Metals, we ensure that every hex bar and rod adheres to strict international standards, guaranteeing dependable performance, durability, and precision for industries that demand high-strength stainless steel components.
Stainless Steel 15-5 PH Hex Bars and Rods are an age-hardenable martensitic stainless steel alloy, featuring around 15% chromium, 4–5% nickel, and 3% copper, all while keeping carbon content low (≤0.07%). This material achieves impressive tensile strength (up to 1,300 MPa) and yield strength (approximately 1,100 MPa) after precipitation hardening. It also boasts excellent hardness (ranging from 44 to 50 HRC), toughness, and corrosion resistance in both marine and industrial settings. The 15-5 PH alloy maintains dimensional stability and superior fatigue resistance, making it ideal for critical applications that require both strength and reliability.
