Located in Amman, Jordan, Sabra Metals stands out as a trusted manufacturer and supplier of Stainless Steel 431 Square Bars and Rods, specifically designed for high-strength engineering applications. Crafted from high-chromium, nickel-rich martensitic stainless steel, these square bars deliver exceptional strength, toughness, and enhanced corrosion resistance compared to standard martensitic grades. Sabra Metals maintains rigorous standards for chemical composition, dimensional accuracy, and surface quality. With state-of-the-art production facilities and tailored supply options, the company caters to the aerospace, marine, automotive, and heavy engineering sectors that demand durable, high-performance stainless steel materials.
Stainless Steel 431 Square Bars and Rods are composed of about 15–17% chromium and 1.25–2.5% nickel, which contribute to their impressive corrosion resistance and mechanical strength. This grade is heat treatable, allowing it to achieve high tensile strength and remarkable toughness through processes like quenching and tempering. In terms of mechanical properties, SS 431 boasts excellent fatigue resistance, good ductility, and strong impact strength. Its unique alloy composition ensures reliable performance even under high stress, pressure, and moderately corrosive conditions.
