· Standard sand cast Nihard will have a BHN of 550 to 650. For grit service where the maximum hardness of silica sand can exceed the minimum hardness of standard Nihard, extra steps must be taken to push the Nihard BHN even higher. This is achieved by modifying standard Nihard through a cryogenic process to increase both hardness and toughness.
