Actually, while it is true that Ti alloys have a modulus of elasticity of 110 GPa and stainless steel is 200 GPa, that means that the steel stretches HALF as much as the titanium for a given load.
A part made from titanium would have to be bulkier than a comparable stainless steel part to provide the same rigidity.
Ti does have a higher yield strength than steel, meaning that it won't stretch or yield permanently as easily as steel does, but if you take 2 identical parts, one Ti and one steel, and pull on them equally, the Ti will stretch almost twice as much as the steel. Keep pulling more however, and the steel part will break first.
okay so maybe I'm a geek
