Stainless Steel 347 is an austenitic stainless steel alloy containing chromium, nickel, and niobium. The niobium stabilizes the steel, preventing carbide precipitation and enhancing corrosion resistance in welded and high-temperature applications. Mechanically, it offers good tensile and yield strength, excellent toughness, and reliable creep resistance. It maintains dimensional stability and structural integrity under prolonged exposure to elevated temperatures and corrosive environments, making it suitable for demanding industrial applications.
