Heat treating A2 and inspection

[@harrisonjpugh]

Hey mate, I am currently trying to get some A2 arrow heads (broadheads) heat treated and I have been told they are too thin (1.75mm) to heat treat because they will deform. What are your thoughts on this? Surely there is a way that it can be done.

Well, who ever told you that they will deform wasn't wrong. There are absolutely ways to get it done, but your probably not going to like the bill for any of them. One way to reduce deformation is to build fixturing to support them during heat treatment. They will still deform, but it may be controllable. This would need a fair amount of experimentation, in other words, scrapped parts and $$$. The second way, which to me would be preferable, would be to make them over size and hard mill them after heat treat to true them up. Then do final grind for the edge/point.

I heat treat a2 parts that are 1.5mm thick, no deformation.
