The scatter plot presents micro-hardness values in H V on the y-axis for three materials on the x-axis: B M D 4140, L P B F cobalt chromium, and Original Grey Cast Iron. Individual raw data points are marked with cross symbols, while dashed horizontal lines indicate mean values. B M D 4140 shows hardness values clustered near 160 H V, L P B F cobalt chromium ranges approximately from 395 H V to 485 H V with the highest mean value, and Original Grey Cast Iron ranges approximately from 338 H V to 395 H V with an intermediate mean value. A legend identifies Raw Data and Mean.Microhardness results for BMD-4140, original gray cast iron and LPBF-CoCr samples
