Annealing ferrous wire in nitrogen based atmospheres

$15.00

This paper first outlines the appropriate nitrogen-plus-additive combinations for a variety of annealing operations, and then focuses on ferrous applications in particular. The different additives used to create these atmoshpheres are reviewed, detailing their purpose and the mechanism by which they act. Atmospheres are recommended for batch and continuous operations, with insights on flow reduction techniques. The batch cycle is emphasized.
