Excavaror mounted hydraulic hammer gat material?
(OP)
I am looking for information on the grade of steel of the Hydraulic hammer "gat" or "bit" that is used to chrush rocks or break up concrete slabs. I am trying to turn a custom adaptor to weld to the end of the bit to hammer plate piles into medium hard sand stone.
Any information on the material, gtaw electrodes, welding procedure, pwht, etc, are used for a high impact bit such as this would help point me in the right direction on this project.

C-0.25-0.3%, Mn-1.2-1.3%, Si-0.5-0.6%, Cr-1.2-1.5%, Mo-0.3%.
These are then oil quenched and tempered to 38-40RC hardness.
A cheaper alternate material is high manganese hadfield steel.
