0.0013~0.0023B) was melted by a 50kg vacuum induction furnace. Teat results showed that with increasing Cu content from 1.0% to2.5%
the precipitation speed of e-Cu in steel and the peak hardness increased; and with increasing Cu%
the yield strength of direct-quenching(DQ)steel after rolling increased from 865 MPa to918 MPa and the yield strength of DQ + 500 ℃ tempering steel increased from 935 MPa to1140 MPa
while the tensile strength and impact toughness of DQ+500 ℃ tempering1.0~2.5Cu steel were lower than that of DQ steel.
