Material requirements for hydraulic plate shears:

1 、 the bonding temperature of cemented carbide is higher than that of high speed steel, so it has higher resistance to adhesive and wear resistance.

2, hardness: hard very near contains a lot of hard carbide, etc. its hardness is much higher than the high-speed steel, hard hardness is near the higher the wear resistance is also better.

3, toughness toughness of cemented carbide than high speed is not suitable for high impact and vibration in the use of.

4 、 thermal conductivity of hard alloy is higher than that of high speed steel.
