From the chemical composition, tantalum's main component is tantalum, while stainless steel contains chromium, nickel, molybdenum and other elements; in terms of physical properties, tantalum has a high density and a high melting point, and belongs to the heavy metal in the metal materials; stainless steel has a relatively low density and a low melting point. In addition, tantalum has higher corrosion resistance and mechanical properties, and has a higher processing difficulty. Tantalum is mainly used in the manufacture of chemical equipment, capacitors, nuclear reactors and so on. And stainless steel is widely used in construction, kitchenware, medical equipment and other industries.
Tantalum and stainless steel have their own unique advantages in practical applications. Tantalum is widely used in special occasions due to its stability and high corrosion resistance in extreme environments.
