What Drives Iron Casting Scrap Rates?

Since the beginning of the Iron Age 2500 years ago, all molten iron has contained free-oxygen atoms and those atoms have significantly corrupted its melting and pouring properties. Free oxygen contamination occurs in tiny amounts but those few parts per million (PPM) alter the iron’s behavior and properties. Deoxidized iron’s properties are so different – and so much improved – that an almost-new material grade results. Few metallurgists understand the role free-oxygen atoms play in […]
