Abstract: Compared with the off-line quenching processing route, the reheating process for austenitizing can be saved
during the on-line quenching process, which shows the advantages of short production cycle, less emission and low cost.
The on-line quenching technology has great development potential in the production of low-alloy wear-resistant steel,
but there are few researches on the preparation of high-strength wear-resistant steel by the on-line quenching treatment.
The microstructure and properties of two high-strength martensitic wear-resistant steels prepared by on-line quenching
were studied by optical microscope, scanning electron microscope, tensile test, impact test and sliding wear test. The
results showed that the yield strength and tensile strength of two steels were above 1 450 and 1 850 MPa, respectively.
