Sabra Metals, based in Amman, Jordan, is a leading manufacturer and supplier of high-quality Stainless Steel 431 bars and rods. Known for their excellent strength, toughness, and corrosion resistance, these bars and rods are manufactured to meet stringent industrial standards. Sabra Metals employs advanced production processes and rigorous quality control to ensure uniform dimensions, consistent mechanical properties, and reliable performance. Serving industries such as aerospace, automotive, petrochemical, and general engineering, the company provides 431 stainless steel bars and rods capable of performing in demanding and corrosive environments.
Stainless Steel 431 bars and rods are composed of a martensitic stainless steel alloy, typically containing 15–17% chromium, 2–2.5% nickel, and 0.15–0.25% carbon. This composition provides high tensile strength, excellent hardness (after heat treatment), good toughness, and moderate corrosion resistance in marine and mildly corrosive environments. 431 stainless steel also maintains excellent fatigue resistance and dimensional stability, making it suitable for precision components that require both mechanical strength and corrosion protection.
