Vacuum Induction Melting (VIM) is used to melt high grade steels or special metals through electromagnetic induction under vacuum. The VIM process is used to produce stainless steel, superalloys, magnetic and battery alloys or high grade non-iron metals. Vacuum Arc Remelting (VAR) is used to continuously remelt a consumable electrode via an arc under vacuum. High vacuum is maintained during the melting process to remove impurities and prevent oxide formation. The VAR process is used to improve the quality and purity of air-melted ingots or metals coming from the VIM process to produce clean, homogeneous metals with improved fatigue resistance and fracture strength.
