Greenville Metals' electric arc furnace melting with AOD refining produces an air melt product for investment casters

For efficient and cost-effective refining of carbon, silicon, sulfur, and other oxidizable elements in stainless steels and many other alloys, the AOD process is a necessary step. Greenville Metals has a 20,000 pound AOD vessel in the electric arc furnace shop and years of experience in its use. AOD refining restores the low gas levels and exact specification chemistry to recycled materials. Greenville Metals’ is a major producer of master alloy for the investment casting industry.

Greenville Metals also produces metallic compounds such as vacuum grade nickel columbium and ferro columbium with exothermic reactions. These reactions utilize the extensive emission controls in our AOD shop.
