steels with good weldability for structural use

[woocash]

Hello, everyone. As from title, they are looking for a type of steel for structural use, which has good weldability characteristics. In particular, it should be a steel that can replace the current 25crmo4 we already use in the company, increasing (as far as possible) the value of the elastic module and that can be more weldable than the current steel, all this without losing too much in terms of maximum yield resistance. the use is the construction of a tubular steel frame for automotive - motorsport.
Some straight?

Do you make a normalization or a softening of the steel you already have and try :tongue:
