Common Hardness Testing Methods And Principles Of Selection
May 23, 2017
Brinell hardness test: measure the annealing, normalizing, quenching and tempering hardness of components and castings and forgings.
Rockwell hardness test: for bulk and finished products and semi-finished products of hardness testing. A ruler for measuring high hardness of quenched parts, small thin pieces of medium thickness surface hardness of hardened parts. B Rod suitable for measuring hardness of annealing, normalizing and tempering. C ruler for measurement of quenching and tempering of the part, as well as thickness surface hardness of hardened parts, to salute the uneven parts not suitable for large organizations.
Surface Rockwell hardness: hardness suitable for thin, small and light or medium thickness surface hardness of hardened parts of general use n rods. T rod for annealing, normalizing, thin pieces.
Vickers hardness: measuring micro hardness, microstructure, phase.
