Hi guys,
I know this may be a dumb question, but when dealing with different alloy and tool steels, what are the main reasons behind the percentage of rebound.
In my limited experience, the RR rail on end at 42lbs and 12" long dented and gad littlle rebound, with a 2 lb cross pein hammer.
The 28" piece at 99 lbs still dented , with only a bit more rebound.
This is old track, both from the same source , supposedly 60 years plus.
I have one more piece to test, it is new and is 39"" long and 150 lbs and a bit beefier.
Finally i just got back my 38 lb chunk of h13 at 54.1 average rc.
It has a dark color all over , and one small sanded spot.
So, I assume the real anvils will have better rebound, but some anvils are cast out of h13 or s7. Yet I have read others say that their large axle on end had the best rebound of all.
So, what are the real reasons behind great rebound?
Thanks,
Jon
