Abstract :The Brinell hardness test method has been in common use for over 100 years. The Brinell test method provides hardness measurement near the deformed or cracked zone. In this work, there is an approach to obtaining several railway steel samples' hardness by using a spherical indenter without optical measurement. Spherical indentation diameter is commonly effected by sink-in and pile-up effect that influences optical measurement negatively. Because of that, the purposed approach aims to obtain average hardness values by using indentation and relaxation curves.Keywords : Brinell hardness, Indentation diameter, Spherical indenter, Pile-up, Sink-in
