Which steel is the strongest?

Tungsten. Tungsten Has the highest tensile strength of any pure metal – up to 500,000 psi at room temperature. It has the highest tensile strength even at high temperatures in excess of 1,500°C. However, tungsten metal is brittle, making it less usable in its pure state.
