Controlling cast iron gas defects. - Free Online Library

1/9/1993· Iron or steel scrap contains about 70-100 ppm of [N.sub.2,] but the opportunity for [N.sub.2] absorption during subsequent remelting is potentially greater in a low-carbon ferrous melt. The presence of a confinuous graphite film indies that the defect is caused by [H.sub.2], but it is difficult to distinguish between fissures caused by either gas.
