What is a high-speed steel saw blade? The following editor will introduce you to what is a high-speed steel saw blade?
High-speed steel saw blade is a steel blade with a cutting blade like a hand saw with a large amount of carbon (C), tungsten (W), molybdenum (Mo), chromium (Cr), vanadium (V) and other elements. After having high thermal hardness. High-speed steel saw blades can be divided into ordinary high-speed steel saw blades and high-performance high-speed steel saw blades according to chemical composition; according to the manufacturing process, they can be divided into smelted high-speed steel saw blades and powder metallurgy high-speed steel saw blades. Due to the high cutting temperature of high-speed steel, there is no significant decrease in hardness when it reaches above 600°C. The cutting speed of saw blades made with it can reach more than 60 meters per minute, and the high-speed steel saw blade is named after it. High-speed steel saw blade applicable machinery: pipe cutting machine, metal circular saw machine, pipe cutting machine, pipe processing machinery, sawing machine tool, milling machine and other equipment. General high-speed steel saw blades can be treated with a special coating. After the treatment, the surface will appear electroplated. The hardness is about 2400HV, which is nearly 3 times higher than that of steam-treated saw blades. The friction coefficient is reduced to 0.55. It is suitable for semi-automatic or fully automatic metal circles. The sawing machine quickly saws seamless steel pipes, iron pipes, bars, etc., at twice the speed of steam-treated saw blades, effectively reducing cutting costs. At the same time, it has better quality when sawing stainless steel pipes.
