Piston Scalers are used for many different surface preparation projects. They can be used to remove heavy rust, scale, paint or industrial coatings from metal surfaces.  They can also be used to rough concrete prior to resurfacing.  The pistons used for these applications range from standard steel (TX-00146) to carbide tipped (TX-00150) or REXALLOY ®™ which is a solid cobalt alloy (TX-00151).  

Please note, solid cobalt alloy pistons (TX-00151) should not be used for concrete surface preparations.  It has been found that silica in concrete causes heat buildup in the REXALLOY ®™ pistons which in turn causes the pistons to wear more rapidly.  REXALLOY®™ pistons should ONLY be used on metal surfaces and primarily for their spark resistance.

REXALLOY ®™ pistons are spark resistant as per parameters used  by O.S.H.A. in reference to U.S. Naval Report No. NGF-T-1-157, NAVORD 5205, agreeing that "ANY" spark produced from impact with this REXALLOY ®™ part will be a cold spark not conductive of ignition in hazardous enviornments.  They are non-magnetic, rust proof and carbide hard.
