Something invisible can often determine the performance of a saw blade

Woodworking saw blade, metal cutting saw blade and HSS saw blade need quality tool steels heat treated. The heat treatment develops hardness, softness, and improves the mechanical properties such as tensile strength, yield strength, ductility, corrosion resistance and creep rupture. But how to ensure the quality of heat treatment? That requires reliable temperature control, uniform temperature field and appropriate temperature and time of heat treatment process.

Saw blade plate usually need to quenching and tempering heat treatment, and heating furnace temperature requirements even, generally require the set temperature within five degrees Celsius temperature difference in different position at the same time, and within the plus or minus five degrees at difference time, so that the organization of saw blade is uniform and the mechanical performance is the best, can meet the use requirement of various saw blade, such as woodworking saw blade, metal cutting saw Blade and HSS saw Blade, etc.

If the use of inferior heat treatment heating equipment, after heat treatment saw blade body structure is not uniform, the hardness of each position is also very different, such as above HRC1 (normal requirements are within HRC0.5). As a result, the stress, strength and toughness of the saw blade body are not uniform, and the saw blade is unstable in use, which affects the cutting quality and service life.

Since the structure and properties of steel after heat treatment are invisible, even with special inspection instruments can not check the quality of each position, so it is very important to use reliable heat treatment equipment and strict operation control when we produce saw blades, including woodworking saw blade, metal cutting saw blade and HSS saw blade.
