Introduction
It is a tungsten-based high-speed tool steel with high red hardness and high-temperature strength. The hardness can still be maintained at ℃ and ℃ respectively. In addition, it also has good high-temperature strength and wear resistance. Properties, its heat treatment temperature range is wide, quenching is not easy to overheat, grinding is easy, thermal processing and heat treatment are not easy to oxidize and decarburize. It has good cutting performance for general processed materials.
The carbide unevenness and high-temperature plasticity of this steel are worse than those of molybdenum high-speed tool steel. The cast structure includes skeletal carbide flakes and ledesite arranged alternately with martensite or troostite, as well as black tissue segregation and white tissue martensite and retained austenite. The as-cast structure and chemical composition of high-speed steel are particularly uneven and cannot be changed by heat treatment. Therefore, pressure processing must be performed to break the coarse eutectic carbides and distribute them evenly, and then use them to make various cutting tools and cutting tools. mold.

Our company specializes in the production of various grades of high-speed steel. New steel grades can be developed according to customers' actual applications. To ensure chemical composition and flaw detection, please bring the original material sheet to contact the production. The electroslag is redissolved and the carbides are small. Among them, the carbide particle size of the cold-drawn material was tested in the United States and reached 1 meter, which is much higher than the national standard. Strictly control the impact of impurity elements such as low magnification and microstructure on steel. The chemical composition follows enterprise self-control standards and can reach around the midline of the national standard. A quality guarantee is provided, the price is affordable, and the specifications are complete. Hot-rolled materials + cold-drawn materials + forged materials are all produced online. The chemical composition and flaw detection are guaranteed. Please bring the original material sheet with you< br/> Our company processes silver bright materials with lathes and grinders
