2.1.3. Hardness

The hardness values of the austenitic AISI 316 and martensitic UNS S46500 stainless steels were 168 ± 6 HV and 521 ± 10 HV, respectively. The values were the mean of 10 measurements acquired using the Vickers microindentation test at a load of 1000 g (Micrometer HV1, Future Tech, FM-700, Tokyo, Japan). Ferritic AISI 1038 steel, used as a reference in this study, has a hardness value of 175 HV ± 10 [21].
