DIN1.3207 High Speed Steel Bar , 2-400 Mm Size High Speed Tool Steel

DIN1.3207 high speed tool steel, high speed steels for metal-cutting tools, Dia: 2-400mm

Application

High-carbon, high-speed steel grade based on Mo, with high resistance to wear, red hardness and toughness. This steel grade displays good grind ability as a result of its low V content. Tools severe mechanical wear, e.g. in cases of small cross-section cuts and high cutting speeds. Particularly suitable for die-sinking cutters and one-lip cutters, and for tool bits in automatic lathes. Also suitable for non-cutting applications, e.g. cold extrusion rams, and for tools for machining aircraft materials, such as titanium alloys, etc.
