Simply a matter of ultimate strength, cutting, and response to brazing? Any experience with those differences for these two steels?
Join the Classic Rendezvous discussion list...you can find the list in Google Groups.
There are several framebuilders there including Brian Baylis who when carrying on discussions about frame materials and framebuilding will cover all the details of what matters when it comes MATERIAL & COMPOSITION versus STRENGTH, STIFFNESS, WEIGHT, FATIGUE AND MODES OF FAILURE.
When following those discussions a lot of myths and commonly held beliefs get torn down and discarded.
Just be ready for lots of emails though...
