Unmarked bolts: Heat Treat or Cryo-treat
I have access to a metallurgy facility that can do heat treat and cryo-treat.
I have 3 unmarked bolts- presumably Polytech/Norinco- and one coming.
Only one checks out lower than 50 HRW on the gauges at the facility.
I can get the bolts re-heat treated, nitrided, or cryogenic dip.
Which would you do ?
