Just starting off trying to make forged blades and will be going to school here shortly. Have read much about always starting with known steels and for beginners using something like a 1075 or 1084. But since I am new to this field and have a chance now, for free, to stock up for later down the road on all thread B7 bolts, should I bring them home or is it worth having?

B7 is a tough steel kinda like 4140. Doesn't have enough carbon to hold a really good edge. I would keep a few pieces of it for other things but, I wouldn't use it as a blade steel.

I agree with George.

I would advise contacting Aldo at the New Jersey Steel Baron and ordering your steel for forging from him.

Thanks for the info, guess its not my day.

His site was out of 1075, 1080 and 1084 in the 1/4" x 1 - 1.5', will try again next week.

Thanks again

Kenneth, another suggestion for known steel here. If Aldo does not have 1075, 1084, you can go with 5160 or his 80crv2. 5160 is a good steel, forges well and is forgiving on heat treat. 80crv2 is 5160 with more carbon and some vanadium for grain refinement. Both would work well for you. Edited to say, he does appear to have 80crv2 in 1/4" x 1" and 1.25". 48" lengths.

Brion gives good advice, this is no exception. I actually prefer 80CrV2 over 5160. For me it seems to move better under the hammer and is easier to finish. I find that I can get a little thinner edge geometry at the same toughness also, this is with my rudimentary testing not scientific research.
