Easy one: 4130 aka chrome-moly aka t45. It is what all race car roll cages and subframes are made out of. It has an infinite fatigue life (unlike aluminum) if properly designed and can be made nearly as lightweight as aluminum. Look up MSI's subframes. Common diameters are .75"-1.5" and wall thicknesses of 0.049"-0.095".
