|GarryinNC said: (quoted from post at 03:22:39 03/03/13) Are square baler needles made of cast iron, cast steel or forged steel? Is there even such a thing as 'cast steel'. My dad has welded several over the years with nickel rod and they look like cast iron when they break. They have always held. Just wondering.|
I do not think any would be forged steel. I imagine most to be either Cast Iron or Cast Steel depending on manufacturer.
Many needles have been repaired over the years by brazing or welding with Ni-Rod, Special Cast Rod, Stainless Rod good for dissimilar metals, 7018 if in a pinch, and even 6011 if real desperate.
Success or failure on the improvised repairs will be more likely if you know the base metal so.....do a spark test (here is the basic of how to do a spark test)
