The general rule is that the more the horseshoe has a small section like the ELAN model, the more it will be possible to obtain important deformations without prejudicing the resistance of the shoe. So it is advisable to hot forge models whitch has wide section like COMETE shoes even if small deformations are necessary.
Forging can be facilitated by heating up to 250 ° C without the mechanical strength and wear of the alloy being significantly altered. But in no case such a heater allows large deformations. This is valid as long as you only heat up.
For large deformations it is necessary to forge between 400 and 450 ° C. However the resistance and wear will be affected from the first heat, and whatever the number of heaters. In this case, quenching after forging never improves the horseshoe strength as it was at the begining.
