One of the most common questions we are asked is related to the difference between the various types of steel from which blades are made.
We made a short video to answer this question:
The consumption of a blade
In general, the wear of a blade depends essentially on the frictional force relative to cutting. The heat developed, although not perceptible at the macroscopic level, is responsible for the wear and tear on steel.
It follows that a blade constructed of heat-resistant elements will have a longer service life.
To simplify, there are 3 possible solutions and they depend strictly on the type of cut, the material to be cut, and the machine used:
Carbon-chrome-wolfram steel, with alloying elements characterized by specific properties of toughness, homogeneity, wear resistance and impact resistance. Ideal for light-duty use
A special HSS high-speed steel with a remarkably long-lasting cut and no serious regrinding problems, an interesting alternative to carbide-tipped blades. Ideal for regular use
Tungsten and cobalt carbide hard metal subjected to a careful sintering process. Ideal for very heavy-duty use
