Forge Ratio
Forge Ratio
(OP)
Hello all, does anyone have advice regarding 4130 minimum forge ratio? In many industry specifications, a forge ratio of 4:1 is seen, while many times 3:1 is accepted. Does anyone know the source of the 4:1 forge ratio as I have been unable to find descriptions in literature shwing this produces a wrought structure throughout (is 3:1 not enough?)

So in summary, more forge ratio = finer grains = better chem homogenation = better mech'l properties. Is 3:1 enough? Probably yes. Is >3:1 better? Yes, maybe. But there are diminishing returns, economic factors on press cycle time, reheating, etc.
