W2Mo9Cr4V2 High Speed Steel Bar
Material Name: High Speed Tool Steel
● Grade: W2Mo9Cr4V2
W2MO9CR4V2 high-speed steel is a tungsten-molybdenum general-purpose high-speed steel that is easy to heat-treat, more wear-resistant, hot hardness and toughness, good grinding, low density, easy to oxidize decarburization. Can make drills, cutters, blades, forming, turning and exploitation, taps, dies, saw blades and a variety of cold stamping die.
● Standard: GB / T9943-2008 (2008.5.13 release, 2008.11.1 implementation)
● Use features
In the 600 ℃ operating temperature, can still maintain a high hardness. Red hardness of the hot deformation of the mold and high-speed cutting tool steel is a very important performance.
(2) wear resistance
Has a good wear resistance, that is, the ability to resist wear and tear. The tool retains its shape and size without being subject to considerable pressure and friction.
(3) strength and toughness
Has a certain strength and toughness, so that tools in the work to withstand the load, shock, vibration and bending and other complex stress to ensure the normal use of tools.
(4) other performance
With a certain high temperature mechanical properties, thermal fatigue, thermal conductivity and wear resistance and so on.
