Panzer Posted May 14, 2016 Share Posted May 14, 2016 (edited) I have some SA-675 GR70 N. I know it is primarily used in welded pressure vessels. My question is (and I'm asking here instead of wasting my time) would it make for a good body for an axe head. It would be a small hand axe. Here are some specs on the material: Carbon 0.27 - 0.31% Manganese 0.79 - 1.3% Phosphorous 0.035% max Sulphur 0.035% max Silicon 0.13 - 0.45% tensile strengths from 55 - 90 MPa I would be fire welding in a piece of O1 for the bit. This will be my first attempt at any type of blade. I have learned to fire weld (finally lol). I just thought I would ask here before I attempted it as I'm no metallurgist and I could'nt find anything in a search. There is the distinct possibility however that I just didn't "search" correctly. Thanks all for your time. Edited May 14, 2016 by Panzer Clarity of purpose. Quote Link to comment Share on other sites More sharing options...
Bo T Posted May 18, 2016 Share Posted May 18, 2016 I'm not sure about the Si, but from what I have read the rest should work OK. Take a small piece of each and see if you can laminate the O-1 inside of the SA-675 GR70 N. What does the N stand for, if anything? You might use a different steel for your bit. If you have trouble laminating the O-1, try a simpler high carbon steel. Quote Link to comment Share on other sites More sharing options...
Panzer Posted May 19, 2016 Author Share Posted May 19, 2016 Thanks Bo. I'm not sure what the N stands for honestly. We have machine parts made and I got the number off the engineering data sheets. I'm hoping to get some time to try just what you suggested this weekend. Quote Link to comment Share on other sites More sharing options...
