Ok so I just found a place that sells "new and used" iron and steel. In the used section they had tool/alloy steel for the same price as the mild (40 cents per pound), so needless to say I got quite a lot. I found a bunch of really good stuff that I'm familiar with (4140, O-1, etc.). I also found an 8 foot section of 1/2x1 D-2 , and a 2 foot section of 2x2 6150.
Now I knew D-2 was air hardening, and I have no experience with air hardening steels, but for the price I couldn't let it go. Ideally I'd like to make some punches, drifts, and chisels for hot work out of this.
The 6150 I assumed was a 50 point carbon steel with a fair amount of chromium. I saw the piece and all i could think was.... 5lb sledge hammer with cross pein.
Please if you have any advice, or comments about forging/HT D-2 and the 6150 I'd like to hear them. Also if the steel is not well suited for the tools I've listed please let me know. Thanks.
