Steel carbide is a kind of carbide carbide with steel as cohesive phase and titanium carbide as rigid phase.It has a very high wear resistance and rigidity (high elastic modulus), and also has a relatively high strength, hardness and a certain toughness.Because the TiC density is small, so the weight is lighter; while the TiC particles are round, the friction coefficient is greatly reduced, and has a better self-lubrication.The alloy also has good thermal shock resistance, can be used in the temperature upheavals. Its outstanding feature is that its processing technology is good and can be heat treatment, heat treatment after the size change is small, deformation in the size error range.In addition, it also has good weldability and malleability.

　　The corrosion resistance of steel carbide carbide varies with the type of steel base. They have good corrosion resistance in seawater and lye, and their corrosion resistance and mechanical properties in other media are shown in Tables 15 and 16.
