IowaHarry Posted January 31, 2009 Share Posted January 31, 2009 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 Quote Link to comment Share on other sites More sharing options...
rthibeau Posted February 1, 2009 Share Posted February 1, 2009 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. Quote Link to comment Share on other sites More sharing options...
IowaHarry Posted February 1, 2009 Author Share Posted February 1, 2009 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. Quote Link to comment Share on other sites More sharing options...
