It is not my territory but for smallish items of a shape able to be forged that process would reduce the energy for heating as well as giving superior structure. Quite a bit of work in assembling and dismantling a mould, whereas the forging is a quick stomp.
Confusion possibly arises with malleable cast iron; I am not sure when that became common. I presumed integral drum/hubs, and diff bodies of 1950s cars are of this. Judging from ones I have dropped, ordinary cast iron drums are not malleable. Pesume malleable iron cannot be welded without complications.
