30Si2MnCrMoVE超高强钢D406A(Steel for Military Use)
低合金超高强度钢30Si2MnCrMoVE,我们采用电渣+双重真空冶炼。或(电炉+精炼+真空+氩气保护电渣)
也在双方协商下也可采用其他D406A生产流程。
Steelmaking process: VIM (vacuum induction melting) + ESR (electroslag remelting),gas content in steel, N2>90ppm.
Steelmaking process: VIM (vacuum induction melting) +esr (vacuum induction melting),N2 is less than.50PPM.
Steelmaking process:EBT(Electric furnace)+LF+VD,gas content in steel, N2> 60ppm
