Do the hardness number of unlike materials give a satisfactory basis for comparing their hardness?
No, the hardness number of unlike materials does not give a satisfactory basis for comparing their hardness because different materials may have different structures and properties that affect their hardness in ways the hardness number may not fully capture. It is more accurate to use a combination of hardness tests and material properties to make accurate comparisons.
What is the hardness of St 52 steel?
The hardness of St 52 steel is typically around 200-280 BHN (Brinell hardness number).
What scale is used to rank the hardness or softness of minerals?
The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.
Is 7on MOHs hardness scale strong?
Yes, 7 on the Mohs hardness scale is considered strong. It indicates that the mineral can scratch minerals with a lower number but can be scratched by minerals with a higher number. Minerals like quartz and topaz have a hardness of 7 on the Mohs scale.
