Stainless Steel 348 is an austenitic stainless steel alloyed with chromium, nickel, and niobium/tantalum for enhanced stabilization at elevated temperatures. This stabilizing addition prevents carbide precipitation, improving high-temperature corrosion resistance. SS 348 offers excellent tensile and yield strength, good creep resistance, and reliable toughness across a wide temperature range. It maintains its structural integrity during continuous heat exposure and provides strong resistance to intergranular corrosion. With its combination of heat stability, corrosion resistance, and mechanical strength, Stainless Steel 348 is ideal for applications requiring durability and high-temperature performance.
