WebAbstract Tantalum is one of the most versatile corrosion-resistant metals known. The outstanding corrosion resistance and inertness of tantalum are attributed to a very thin, impervious, protective oxide film that forms on exposure of the metal to slightly anodic or oxidizing conditions. WebTantalum is inert to Sulfuric and Hydrochloric acid below 300°F. Attack up to 400°F is not significant and is common use up to 500°F. It has good thermal conductivity and erosion resistance. It forms easily, is highly workable and weldable. This makes it an ideal tube material for corrosion resistant Reactors.
