What are the different uses of high -speed steel?
High -speed steels are a group of high -performance steel alloys used to produce pieces and parts of machines used in demanding high -speed machine tools. There are several degrees of high -speed steel (HSS), all of which include carbon as a common alloying element except for various other ingredients such as tungsten, cobalt and vanad. Unlike ordinary instrument steel, the composition of high -speed steel alloys allow to withstand very high operating temperatures without losing their hardness. This characteristic makes them ideal for the production of drills, milling bits and reamers. Beautiful tools, gear cutters and SAW blades are also commonly produced from HSS. Although effective, they did not hold their hardness very well at increased operating speeds. Progress in metallurgical science, such as the replacement of tungsten Molybdenum joke, created by additional possibilities of heating and gave birth to high -speed steel. These steels have a carbon content ranging from 0.65 to 1.1 percent and perOther banging components such as tungsten, vanadium and cobalt are also playing. In general, they are very hard, with average HRC60 values and are able to maintain their temperament or hardness, even at high operating temperatures.
Several other HSS products have shown many new uses. These include coating with substances such as titanium nitride and titanium carbide, which not only increases the hardness of the tool surface, but also lubrication. This prevents the cut material from being or holding or holding a bit due to high operating temperatures caused by friction. The coatings also serve to reduce temperatures generated during cutting, ensure cleaner cuts and better tool life.
This characteristic allows high -speed steel ideal for making tools and bits of tools used in demanding high and high frictions where deep long cuts are made rapidlyA shadow that was not previously possible with older tools. These applications include tool bits used to rotate, shape and milling. High -speed drill bits are also usually made of HSS. Although they generally do not work at extremely high speeds, reamers, gear cutters and SAW blades are also made of high -speed steel due to high temperatures generated during their use. For information, when buying these high -speed steel products, they are generally marked with a stamp of "HSS" or "HS" for easy identification.
