View Full Version : Alloy for mud pump rods?

I retrieved several from the scrap bin. In use they have a stuffing box seal running on the OD and have a very nice surface finish. Not surprisingly they machine very well. Does anyone know what alloy they are made from?

I've made a bunch over the years,specs ranged anywhere from 1144 stressproof to 4140 and 316 stainless so they could be anything.
