Stainless Steel 431 Plate is a temperature- and corrosion-resistant alloy designed for use in the industrial, chemical, and marine industries. It contains a high chromium content (about 18%), which provides excellent resistance to corrosion, plus nickel for toughness and stability. The plate also includes low carbon levels for formability and good weldability. Its composition comprises 16–18% Cr, 1% Mn, 0.2–0.3% Si, 0.7–1% Ni, ≤0.04 Pb, ≤0.03 S, ≥14 N. This combination makes it an ideal choice for applications that require reliable performance in elevated temperatures or corrosive environments with high mechanical strength under stress, such as valves & pumps operating in the oil & gas industry or offshore rigs exposed to salt water because of its superior durability and long-lasting performance characteristics compared to other steels available on the market today.
Stainless Steel 431 Plates offer excellent resistance to wear and corrosion, making them a popular choice for many applications. Their strength makes them suitable for industrial and residential use, from kitchen countertops to heavy-duty construction components. Additionally, they are easy to cut and machine and have good formability and weldability. As a result of these properties, Stainless Steel 431 Plates find many uses in the automotive, aerospace, and marine engineering sectors, as well as medical applications such as surgical instruments.
