What makes ROCKEATER hydraulic hammer breaker steels superior? Quite simply, it is the heat treating process and selection of material.

  The critical factor in the manufacturing of a ROCKEATER is that the heat treating, quenching, and tempering of the bars is performed with the steel in a vertical position. This heat treatment prepares the steel to absorb the vertical impact of the hydraulic hammer. The horizontal heat treatment performed by some others allows for deflection of the bars, which can cause premature failure.

  Each ROCKEATER starts with a bar of steel alloy specifically selected for the diameter of the point being made. These bars are manufactured to high tolerances on CNC machine tools to insure proper fit. Computer controlled for quality and consistency that earned the ISO 9002 registration. Then, the important process of heat-treating begins.

  Each point is heat treated in custom designed furnaces that were commissioned solely for the purpose of making breaker steels. The specially designed induction hood heats the steels through to the core to the precise temperature. The steel is then quickly quenched in special cooling baths to harden the metal. Finally, a tempering process is used to increase the impact resistance and to bring the steel to the correct Rockwell hardness for the job.

  The outside Rockwell hardness is 48 to 52 and gradually (linear) decreases to a center hardness of about 38-40. This gives each Rockeater unmatched ductility and flexibility to allow for abusive use.Some manufactures use nickel and chrome content, which can only be hardened to a 43 Rockwell. This material is surface hardened to a 48 -50 Rockwell but only to a .4 mil (skin) thickness by a carbon gas process.
