Titanium is NOT the strongest metal. It is often thought of as the strongest but actually it has one of the highest strength to weight ratios. I.e., for a metal that is so light-weight, it is extremely strong. Typically it has a ultimate tensile strength of up to 170,000 psi. Another unique property is that its strength does not deteriorate in high temperature applications. This makes it ideal for use in aerospace especially engine components.
There are many metals much stronger than this. Two stainless steels that come to mind are 17-4PH and 15-5PH which can achieve Ftu of 180,000 to 200,000 psi through heat treatment.
Inconel 625 which is used in the aerospace industry, typically in the production of high-strength fasteners used in critical joints can achieve ultimate shear strengths of 220,000 psi.
Intermediate alloy steels such as 5Cr-Mo-V has an Ftu of up to 280 ksi. Also low alloy steel such as AISI 4130 used in aircraft landing gear has extremely high bearing strength, tensile and compression strength.
