Leeb Hardness Test Blocks, made of carbon or alloy steel, are used for calibrating hardness testers in accordance with ASTM E18, DIN 50156, and ASTM A956, featuring a tested area with factory calibration indenter prints and an identification number on the lateral surface.
Hardness testing blocks, made of carbon steel are used to calibrate metal hardness testers and come in various standard nominal values, such as 25 HRC, 45 HRC, 65 HRC, 90 HRB, and 83 HRA.
Hardness testing blocks are used for calibrating metal hardness testers, available in nominal values like 100HB, 200HB, 300HB, 400HB, and 600HB, in compliance with ASTM E10.
Hardness testing blocks, available in various nominal values (200HV, 450HV, 800HV or other by request) and loads, are used for calibrating metal hardness testers and meet the ASTM E92 standard.
