讨论了硬度值不超过HB 200的情况下,便携式里氏硬度计用于大型工件现场测试时测量值偏低的影响因素。针对S355J2G3和A240CrS41500两种材料进行了测试,准确估计出测量误差范围,并绘出硬度曲线,提供了准确的技术数据。
Discusses the impact of low value measurements on a portable Leeb hardness tester for on-site testing of large workpieces with a hardness value not exceeding HB200. For S355J2G3 and A240CrS41500 two materials were tested to accurately estimate the measurement error range and draw the hardness curve provides accurate technical data.
