M35 Tool Steel in Thread Rolling Applications: Why Cobalt Content Matters - TGK Special Steel
Thread rolling is a high-precision metal forming process widely used in the manufacturing of fasteners, bolts, screws, and threaded components. The process involves applying pressure to deform metal and create threads without cutting material. Because of the high stresses and friction involved, the tooling material must possess excellent wear resistance, hardness, and heat resistance. This is where M35 tool steel becomes particularly valuable, making the role of a reliable M35 steel supplier extremely important. M35 is a high-speed steel that contains approximately 5 percent cobalt. This cobalt addition significantly enhances the steel’s hot hardness and red hardness, meaning it can maintain its hardness even at elevated temperatures generated during high-speed operations. In thread rolling applications where tools are subjected to continuous friction and pressure, this property is essential. One of the key advantages of M35 tool steel is its ability to withstand thermal str...
