2. Material analysis of blade
The hardness of the material W6Mo5Cr4V2 for the tin breaking blade is 58-62
HRC after heat treatment, and the hardness and the wear resistance are very
high, so the abrasion is very small between the blade and the tin wire.
3. Service life of blade
It is predicted that the service life of the blade is about 1 year according to the
material properties of the blade and the force bearing condition of the tooth tip.
The failure mode of the blade is mainly manifested that when the holes on the
tin wire are different in size, it indicates the blade has been abraded seriously.
At this time, it is suggested that the customer should replace the blade.
