How many coatings are there on high-speed steel saw blades? At present, there are four common coatings on high-speed steel saw blades: colorful coating, oxide coating, titanium coating and rose gold coating. These four coatings also have differences in performance.
1. Colorful coating Colorful coating is one of the common coatings in high-speed steel saw blades, and its scientific name is surface chromium nitride alloy coating. Therefore, this kind of coating is often named after the colorful feeling after light dispersion under the light. Compared with ordinary high-speed steel saw blades, the high-speed steel saw blade with this coating has the characteristics of lower cutting resistance and high wear resistance. From the perspective of use, high-speed steel saw blades with colorful coatings are often used for cutting, blanking and milling of metal materials such as stainless steel pipes and bars. After the material is cut, it has the characteristics of less burrs on the section and good toughness of the saw blade.
3. Titanium-coated high-speed steel saw blade with titanium-coated gold. The surface is obtained after a special PVD coating treatment, which makes the saw blade appear golden. From the data point of view, the hardness of the high-speed steel saw blade after the treatment of titanium gold coating has reached 2300HV. At present, this kind of titanium-coated high-speed steel saw blade is commonly used for automatic metal circular sawing machines. Cut seamless steel pipes, bars and other metal materials. Not only can effectively reduce the cost of sawing processing, but also can ensure the sawing effect.
4. Rose gold coating is also a coating processed by PVD coating technology. The high-speed hacksaw blade with this coating is especially suitable for use in high cutting speed and high feed speed. Generally used for fine processing of metal materials. Compared with other types of coated high-speed steel saw blades, the high-speed steel saw blade with this coating can effectively reduce the probability of debris sticking to the saw blade. The hardness of its surface can ensure the stability during the sawing of materials. Rose gold coated high speed steel saw blades are generally used for sawing of materials such as copper alloys and titanium alloys.
