It is used to verify and calibrate Rockwell hardness testers before and during use, ensuring accurate readings across the full testing process. The block provides a known reference surface that technicians check against their instrument output to confirm the tester is performing within acceptable tolerance. Quality control technicians, metallurgical lab personnel, and industrial inspectors use this block as part of standard instrument verification routines.\u003c\/p\u003e\n\u003cp\u003eThis test block is suited for calibration and verification of Rockwell hardness testers operating on the C scale, which is commonly applied to hardened steels, tool steels, and other hard metallic materials. The 62 HRC rating makes it appropriate for validating tester performance at the upper end of the Rockwell C range, where many hardened cutting tools, dies, and wear-resistant components fall. It ships as a single-piece block ready for immediate use in a lab or shop floor environment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRockwell C scale calibration reference rated at 62 HRC\u003c\/li\u003e\n  \u003cli\u003eHigh hardness range designation for upper-range tester verification\u003c\/li\u003e\n  \u003cli\u003eSingle-piece block format for straightforward handling and storage\u003c\/li\u003e\n  \u003cli\u003eProvides a known reference surface to confirm hardness tester accuracy\u003c\/li\u003e\n  \u003cli\u003eApplicable to hardened steels, tool steels, and similar hard metallic workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Rockwell hardness testers that operate on the C scale.

Place the block on a clean, stable anvil surface free of debris before taking calibration readings. Follow the hardness tester manufacturer's recommended procedure for the number of verification indentations and their placement on the block surface. Avoid taking readings too close to the block edge or to previous indentation sites, as these can produce inaccurate reference values.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScale Type\u003c\/strong\u003e: Rockwell C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Hardness\u003c\/strong\u003e: 62 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Range Description\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.58 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41114600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HTB00062B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":68387387834674,"sku":"HTB00062B","price":155.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddaa7b225f2ce527b146a59d1c498d51.jpg?v=1793903872","url":"https:\/\/voomisupply.com\/products\/value-collection-htb00062b-rockwell-c-hardness-test-block","provider":"Voomi Supply","version":"1.0","type":"link"}
