Ingot (AOD Refining)
AOD, Argon Oxygen Decarburization, refining provides tight chemistry control and high levels of metal purity for your application.
This ingot refining process produces steel with low carbon properties (.01% or lower) and low silicon levels, which, in turn, creates a metal that has better weldability (can reduce weld electrode use by over 50%), and is more corrosion-resistant, malleable, and heat resistant.
This ferrous metal, typically stainless steel, refining process is increasingly used by the premier members of the foundry industry like MetalTek, to improve alloy performance. We control cost by capturing and reusing machine chips and can recycle raw materials with guaranteed high purity.
Our AOD steel capability at multiple facilities supports MetalTek's standing as a leading master melt foundry. We routinely pour over 450 alloys, including many proprietary grades. Specify AOD in your specifications to significantly improve your alloy’s properties.
MetalTek also utilizes our AOD capacity at multiple facilities to generate highly refined certified stock for ingots. AOD-refined ingot material is available in dozens of ferrous grades. It is used extensively by investment foundries that demand high integrity metal in controlled quantities. Our toll melting services turn your scrap into certified stock.
