High Speed Steel

DESCRIPTION
BÖHLER S290 MICROCLEAN – “The hard stuff”
The unusual alloy point of this bridge material between carbide and high-speed steel gives it a hardness of up to 70 HRC. In addition to its hot hardness and good wear resistance, its compressive strength is one of the most important properties of this powder-metallurgical high-speed steel class.
Property Features

• Toughness & Ductility: good
• Wear Resistance: very high
• Compressive strength: very high
• Edge Stability: very high
• Grindability: good
• Hot Hardness (red hardness): very high
