aquamanlr Posted December 18, 2008 Share Posted December 18, 2008 I have been around for awhile, but never posted on this forum before. I have some metal cutting bandsaw blades, 1 1/4" wide that is marked Omada MGLB 5-7P. I have heated it to non-magnetic and cooled it overnite in a bucket of vermicalite. I then broke a piece. It broke almost straight across like a file would. What I would like to know is if this is suitable metal to make a fillet blade. I was not able to post a photo.

Feukair Posted December 18, 2008 Share Posted December 18, 2008 The process you performed was annealing which would have softened normal carbon steel of those dimensions to where you couldnt have broken it, it would have just bent. So i would guess its some kind of air hardening steel which i don't think is the kind normally used to make knives. However it you want to make a fillet knife, which is usually thin and flexible then that steel is already the shape you need almost. Maybe you could just grind it to shape (if you have any left that you havent heated) keeping it cool while you grind. No reason to re-heat-treat.

Frosty Posted December 18, 2008 Share Posted December 18, 2008 Welcome aboard Leroy, glad you delurked. Feukair pretty well covered your question, it's most likely air hardening steel. However, if you'll click on "User CP" at the top of the page and edit your profile to show your location you'll probably find folk living close enough to lend you a hand personally. It also makes it easier for us old farts to remember who is where when we're traveling, I never know when I might need a nap or hot lunch.

son_of_bluegrass Posted December 18, 2008 Share Posted December 18, 2008 I've heard some folks claim that metal cutting bandsaw blades are commonly M series. I don't know for sure. If so it is an air hardening steel. I can't comment on its forgability. Some of the air hardening steels are made and heat treated in such a way that they can be ground without worrying about overheating. ron Quote Link to comment Share on other sites More sharing options...
aquamanlr Posted December 18, 2008 Author Share Posted December 18, 2008 Thanks for the replies. I think that I will grind a fillet out of it, and use it next summer. I am hoping to do some fishing in Idaho. I still have a few ft. of this stuff. LeeRoy Quote Link to comment Share on other sites More sharing options...
