In　this　study,　a　wear-resistant　Cast　Boron　Steel　(CBS)　of　nominal　composition　0.25%　C,　1.18%　B,　1.27%　Cr,　0.85%　Mn,　and　0.69%　Si　was　oil-quenched　at　different　temperatures.　The　effect　of　quenching　temperature　on　the　microstructure　and　wear　resistance　of　CBS　was　investigated.　Moreover,　the　wear　resistance　between　CBS　and　high　chromium　cast　iron　was　compared.　The　results　show　that　a　martensite　matrix　can　be　obtained　by　quenching　from　900　to　1050　A　degrees　C,　and　the　wear　resistance　of　quenched　CBS　is　excellent,　which　reaches　the　level　of　high　chromium　cast　iron.　The　reason　behind　the　fact　that　CBS　has　excellent　wear　resistance　is　discussed.
