0. 10Nb)is melted by 5 t medium frequency induction furnace+2 t vacuum electro-slag remelting furnace
then forged and hot rolled to φ45 mm bar products
and the test specimens solid-solution-treated at 1000 ℃ for 30 min +cold-treated at -70℃ for 2 h are aged at 400~600 ℃ for4 h. Test results show that with aging at 450 ℃
the strength of steel 0Cr15Ni5WMoVNb is up to maximum value with main quasi-cleavage fracture and low impact energy-40J
with increasing aging temperature the impact energy of steel increases obviously and strength decreases
and with aging at 510 ℃ the steel has excellent strength-toughness i.e.tensile strengh Rm 1300 MPa
yield strength Ro.21100 MPa and impact energy Akv 100 J.
