High speed steel is characterized by high hardness, wear resistance, but poor toughness. When the hardness is too high, it is easy to collapse in use. Moderate hardness, good toughness, it is hard to wear in use. How to set the value of positioning with high speed steel, hardness and toughness, how good is the eternal subject of workers, workers of tool heat treatment.

Two, about fakes

There are a lot of saw blade and the market, and very cheap ten dollars, those are 65 Mn strip do, punching the saw tooth, saw no way, good recognition, high frequency heat treatment and then annealing, of course, can also be used, but also a very sharp knife, 65 manganese understand know what material. It is not often keep the edge grinding, if you really don't recognize on the stove burning, burn with daopi, see what the situation really is not just the front annealing.

Three, matters needing attention

Steel blade ends with a pin hole position is not part of the work is a semi annealed state, the hardness is not high, this is not to work in Jiaoduan pin, also because the torsion force of blade from its brittle fracture.
