Excellent wear resistance, equivalent to 266 times of manganese steel.

High hardness. Far more than stainless steel in wear resistance.

Light weight, its density is 3.9g/cm3, can reduce equipment load.

The material itself is resistant to the high temperatures of 1600℃ and has good self-lubrication. There is no expansion caused by temperature difference between 100℃ and 800℃.

The material itself has the characteristics of corrosion resistance and can be used in the fields of strong acid, strong base, inorganic, organic salt, seawater, etc.

No magnetic, no dust absorption, low noise; Can be used in demagnetization equipment, precision instruments and other fields.
