The density of EN31 steel is around 7.85 g/cm^3.
EN31 is considered to be a challenging material to machine due to its high hardness and toughness. Specialized tools and techniques are often required to effectively machine EN31 steel, and it is known to have a tendency to work harden during machining. Proper cutting speeds, feeds, and tool materials are key factors to consider when machining EN31.
EN31 is steel that has a hardness measurement of 63HRC. The Brinell-Rockwell hardness of the material ranges from 59 to 65.
