what uses does D-2 tool steel have does anyone know and is there any problems heat treating

Jackson: Have you done any reading in the knife making and heat treating sections on Iforge?

However seeing as you'd rather just ask than do a LITTLE research I'll give it a shot with maybe 3 minutes of reading. Yes D2 has LOTS of uses. YES it requires advanced equipment, knowledge and experience to properly heat treat. It's air hardening so it's a serious trick to keep it from hardening.

Try doing a web search, IGNORE Youtube, blogs, etc. and read the MANUFACTURER'S specs and recommendations.  Page 1 on Speedy Metals site will tell you more than you will understand.

I'm not poking you honestly but you'll learn so much more so much faster if you do a little real research. No, social media is NOT real research. Walk with me and listen to me tales, me boyo I'll learn you about reading about other people's mistakes and successes so you don't have to screw up as much stuff as I did.

No problems heat treating D2 if you follow the instructions EXACTLY; probably need a computer controlled ramping heat treat furnace but that's not a problem; just a requirement.

Machinery's Handbook section on tool steels mentions D2 being used for: coining tools, thread rolling dies, dies for long runs, lathe centers, hot trimming dies, tools with keen edges: knives, razors

NOT A STEEL TO LEARN SMITHING ON; A STEEL FOR ADVANCED WORK as such it makes decent trade stock at blacksmith conferences---not as good as H13 or S7 or O1 or 52100 or...

After looking at your profile I see you are 14. Same age I was when I started this trade. 13 years later and I'm still learning more every single day. I did notice you do not have your location listed in your profile however. You should add it since there may be a Smith close by who can help you along. If you live near me, I'd say stop by my shop whenever you want and I can help you out, but I don't even know which country you live in.
