What kind of material is the saw blade made of?
Saw blades are usually made of steel.The blade is provided with a steel strip blade, blade is the main part of the saw blade.
Hacksaw blade is used in most carbon tool steel, machine saw most is "wind" steel (W18Cr4V) manufacturing, low carbon blade, hardness and strength than the steel with low wind, no wind and durable steel.Saw blades are common in most cases, and there is no need to choose. But for higher hardness materials, or choose wind steel saw blade is suitable.
Different saw blades with different pitch should be changed for cutting saw.Most of the manual saw blades are made of carbon steel, and two kinds of carbon, tool steel and carburizing steel are specified according to the type of steel and process. Carburizing steel is made of low carbon steel saw, and then carburizing quenching. Cheap carbon blade.Most of the machine saw blades are made of high speed steel (W18Cr4V, etc.) and tungsten vanadium steel. The price is more expensive.Carbon blade cheap, hardness and strength and hot hardness than high speed steel low cutting speed allows very low. Among them, the biggest difference is hot hardness, and hardness is very small. And no matter what kind of saw blade, the material that allows processing is very low hardness, hardness is similar, but the strength of the material is very different.So for the same cutting speed and working condition (manual, motor), the first choice to adapt to the cutting speed of the saw blade material (carbon blade could not be used to machine); then according to the cutting of different materials, selection of saw tooth shaped, soft material (low strength, with large pitch, the teeth have larger anterior horn and posterior horn; whereas the smaller tooth shape, tooth pitch).
