WEXCO® 666   

Nickel-boron base iron with a high hardness, martensitic structure in cementite matrix.  Excellent abrasion resistance with a low friction coefficiency (0.07) for prevention of galling.  Provides a service of at least 4 times that of nitrided barrels, and a hardness range of Rockwell C58-65 (at 70oF).  Recommended for use when abrasive materials are being processed.
