Hi all,

A friend has come up with E 4330 steel. 4x5x12. He plans to use it for weights. From what little I can find on it it seems to be a high alloy which would serve a better purpose than weights on a truck or tractor. Can anyone tell me more about it and maybe what a dollar value it might have.

thanks, Harry

4320 - 4340 Steels are about the same except for carbon content:
C 0.38-0.43 Mn 0.60-0.80 P 0.035 (max) S 0.04 (max) Si 0.15-0.30 Cr 0.70-0.90 Ni 1.65-2.00 Mo 0.20-0.30

4340 is advertised by McMaster-Carr as a high strength shock resistant alloy steel specially designed for applications involving severe impact, wear, heat, and stress, and as a highly alloyed steel (nickel, chromium, and molybdenum) is stronger and more shock resistant than 4140.

2 1/2 inch diameter rounds go for $110 a foot....it is not a cheap metal. If I had that chunk, I'd cut it up for hammers.

Thanks, I've been trying to tell him there is plenty of scrap to make weights out of. I might try to buy one stick from him.
