Hardness introduction of chainsaw file

Modern chainsaw files are generally made of carbon steel by rolling, forging, annealing, grinding, cutting teeth and quenching. Generally, the hardness is about HRC60 degrees. Such hardness can't be super hard, so it can't be called super hard chain saw files. When the hardness of the saw file reaches HRC 68-70 degrees, it is really a super hard saw file. At present, only XLIW saw file has a hardness of HRC 68-70 degrees, and only XLIW is a real super hard saw file. It is difficult to produce super hard saw file by traditional heat treatment process,

Generally, the hardness of chainsaw chain is HRC 54-56 degrees. At present, the hardness of the chainsaw file sold on the market is about HRC60 degrees, and that of the world's first brand STIHL is only about HRC60 degrees. Because the hardness difference between the chainsaw file and the saw chain is only HRC 4-6 degrees, the chainsaw file is blunt when cutting the saw chain. Generally, more than two electric chainsaw files are consumed for one saw chain. The hardness of XLIW chainsaw file is HRC 68-70 degrees, which is nearly 14 degrees higher than that of the saw chain, which makes XLIW file have a service life that other brands cannot. Generally, only two saw chains can consume one XLIW file.
