forged blanks
Forged blanks will likely be stronger than the typical cast pieces due to the grain alignment. They will not be stiffer however, because the random grain alignment of a casting makes the part more resistant to bending (harder). A forging will have higher ultimate strength, just less initial stiffness. As far as a bronze part having the same tensile strength as a (316L) stainless part, probably not, but it depends on the bronze. There are more recipes for bronze than chicken soup. By the way, I believe all commonly available stainless props are investment cast.
