I was given almost 100 feet of Bandsaw blade a guy here on
s.e.m. tested it for me and it turns out to be a Boron steel...
0.07%C
0.68%Mn
0.002%B!
0.27%Si
1.15%Cr
1.05%Mo
0.67%Ni
0.17%V
0.04%W
(it was low on P, S, Ti, Al and Cu)
Read that 0.002%B is high enough to make it harden with Boron.
But how?
I go by what I call the "arrest point method" (eyeball) to heat
treat carbon steel and hadn't had any luck changing this bandsaw
blade's hardness. Got any advice? :)
