"C" Scale Rockwell Hardness Test Block
Our premium "C" Scale Rockwell Hardness Test Blocks are engineered to deliver a dependable reference standard for laboratory calibration and material validation. Manufactured from the highest quality steel, these blocks undergo a specialized heat treat and cold treat process which insures maximum consistency, structural stability, and superior repeatability across all testing routines.
Crafted in a heavy-duty round block configuration measuring 2½" in diameter, this testing standard is indispensable for aerospace quality control, MRO facilities, and specialized metal fabrication workshops. Its uncompromising construction eliminates data volatility, allowing metrology technicians to audit high-load hardness testers with absolute confidence.
Advanced Cryogenic Treatment
Manufactured from premium tool steel subjected to proprietary heat and severe cold treat processing, eliminating internal stress factors to provide maximum material consistency.
High-Load Calibration Standard
Optimized explicitly for standard C-Diamond 150Kg testing configurations, offering stable verification surfaces across the full HRCs 25 to 63 hardness scale.
Exceeds Metrology Criteria
Precision-lapped and audited to deliver an accuracy profile that comfortably exceeds ASTM E10, E92, and E384 global standards for industrial testing compliance.
