George Metals, a leading manufacturer and supplier located in Houston, USA, focuses on Stainless Steel 431 Flat Bars and Rods, designed for applications that demand high strength and resistance to corrosion. This martensitic stainless steel grade features a high chromium content and controlled nickel levels, providing outstanding toughness, tensile strength, and moderate corrosion resistance. Meeting ASTM A276 and other international standards, these bars and rods are perfect for aerospace, marine, and mechanical systems where both strength and surface finish are essential. George Metals offers precisely sized, heat-treated 431 bars with quick turnaround times and technical support to fulfill rigorous industrial and structural needs.
Stainless Steel 431 Flat Bars and Rods consist of about 15–17% Chromium, 1.25–2.5% Nickel, along with balanced Iron and low carbon content (around 0.20%). This martensitic stainless steel provides a remarkable combination of high tensile strength (approximately 850–1000 MPa), good hardness (up to 40 HRC), and moderate resistance to corrosion. It performs admirably in mildly corrosive settings and under mechanical stress. Heat treatment boosts its strength and toughness. George Metals guarantees precise metallurgical standards, consistent dimensional tolerances, and certified mechanical properties for demanding industrial and structural engineering applications.
