Model Number: high speed steel-01-42
Key Specifications/Special Features:
M42 high speed steelApplications: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.Steel Grade:C:1.05 - 1.15Si:0.15 -0.50Mn:0.15 - 0,40P:<=0,030
S: <=0,030

Characteristic: High performance tungsten-molybdenum high speed steel, excellent performance of hardness, red hardness, thermoplasticity, machinability. Only weak in toughness
High speed steel got hardness method:
1. Salt bath hardening or vacuum hardening
2. The temperature 1180-1200°C, if need high hardness add 10°C 3. in the temperature 560°C, tempering more than 3 times. The most important: control hardening temperature and time.
