CHARACTERISTICS OF THE MATERIAL
Another fundamental feature of Hard Metal is the "Resistance to cross fracture" which can give an approximate indication of tenacity. In principle, this feature increases with increasing Co content up to a maximum of 20% and decreases with increasing TiC content.
The "Elastic Modulus" is another important feature of Hard Metal. While in high speed steel the value of this characteristic is 220000 N / mm2, in Hard Metal it varies from 500000 to 640000 N / mm2.
Note that in Hard Metal with elastic deformation an appreciable plastic deformation does not follow but rather fractures.
