The invention provides a novel low-cost wear-resistant
pipe steel X65 steel plate which comprises the following chemical components in percentage by
mass: 0.04-0.10% of C, 0.10-0.40% of Si, 1.40-1.60% of Mn, at most 0.02% of P, at most 0.015% of S, 0.015-0.060% of Als, 0.005-0.06% of Ti, 0.20-0.70% of Cr, 0.02-0.07% of V, and other Fe and residual elements. The production method comprises the following steps: converter
smelting, LF (
ladle furnace) refining, VD (vacuum
degasser) vacuum treatment (optional),
continuous casting,
slow cooling of
casting blank, heating, TMCP (thermomechanical rolling process) rolling,
slow cooling, and hardening and
tempering. By using the novel composite microalloying component design idea and simple effective
process design, the method lowers the production cost of the steel plate, ensures the mechanical properties, ultrasonic flaw detection index and other indexes of the steel plate, and enhances the
wear resistance of the steel plate. The steel plate produced according to the scheme has the advantages of uniform properties, excellent flaw detection quality and certain
wear resistance, can be widely used in the fields of
petrochemical industry,
coal chemical industry,
machine manufacturing and the like, and has favorable popularization meanings.
