Bandsaw blade welding

[Highpower]

I've been trying to read up on heat treatment as of late and have come across a few tidbits that I never would have believed before. (Heat Treatment, Selection, and Application of Tool Steels ~ Wm. E. Bryson)

Things like the heat from grinding can produce 2000 - 3000° F in steels. Granted mind you - that is in reference to surface grinding larger pieces of steel than a band saw blade. I've never welded a saw blade in my life, so how that translates I don't know.

I have learned that one size does not fit all. Needed temperatures vary depending on the amount of carbon in a particular alloy. Higher carbon content requires a higher critical temperature range to make the transition. And tempering temperatures can be WAY different between alloys. But so far my understanding is the same as Dave's that tempering stabilizes freshly formed martensite. (hardened steel) If the steel is annealed it is returned to a pearlite structure (unhardened) and therefore there is no "martensite" grain structure present to "temper".

Which begs the question - what steel alloy(s) are bandsaw blades made from?

Ugh. Still so much to learn...
