Product Name: carbon tool steel
Model: T10
Standard: GB / T 1298-1986
● Features and application:
The steel strength and high wear resistance than T8 and T9, but the hot hardness is low, not high hardenability and hardening deformation. Suitable for the manufacture of cutting conditions are poor, higher wear resistance, and is not a sudden and severe vibrations, requires a certain toughness and a sharp knife-edge tools, such as turning, planer, drill, cutter, low accuracy and shape simple measuring tools (such as card board, etc.), can be used without a large impact on the wear of zero
