Nitride-bonded SiC wears less intensively than steel types commonly used to manufacture parts for soil working applications in light and medium soil conditions, and excels in abrasive environments. Boron steel and C+ Cr+ Nb padding weld wear more intensively and should not be considered replacement options; SiC is much more resistant to brittle cracking than its tested steels counterparts.
