Material Characteristics
6542 steel is characterized by high hardness, wear resistance and thermal hardness (also known as red hardness), when the cutting temperature is as high as 500~600℃, the hardness has not decreased significantly, it can be cut at a higher [TJC STEEL]speed than low alloy steel.The disadvantage is that it is easy to oxidize and decarbonize.
Applications
6542 steel is mainly used to manufacture various cutting tools with high cutting speed, heavy load and high working temperature, such as[TJC STEEL] turning tool, milling cutter, hob, planer tool, broach, drill bit, tap, etc. It can also be used to manufacture cold and hot deformation molds, high temperature springs, high temperature bearings and so on, which require high wear resistance.
