[TheForge] Old band saw blade

[Dave Smucker]

For those of you that may not know - L6 is basically  - 4370  -  like 4340 but with 70 points of carbon instead of 40.  Very good steel and you can heat-treat it just like it was 4140 or 4340 but it will be harder.  Don't forget to temper.

Thanks, L-6, even if it has carbide teeth brazed onto it?

15n20 usually for high speed m42 blades. I believe wood mizer are 15n20 also.

L6 for circular.

You can test by seeing if a test strip will air harden..

I have a piece of old band saw blade without carbide teeth, probably from a Wood Miser. What kind of steel is it likely to be? 15N20 maybe? What steel is used in circular saw blade that has carbide teeth? Thanks, Ron ______________________________________________________________
