Description
A low cost adaption of bottom teeming of ingots, contact pouring, is found to raise the toughness of super duplex stainless steels by nearly an order of magnitude (ten times) by reducing the density of the damaging bifilm defect population. Simple additional features to divert the first damaged steel through the runner and away from the ingot, is predicted to further improve the ingot, achieving a higher quality than a vacuum cast ingot. Cracking of rolled or forged products is expected to be eliminated. Other benefits of elimination of the sensitization of steels by heat treatment, hydrogen embrittlement, and stress corrosion cracking are also expected.
