... is necessary to provide rod of even better surface quality. This can be achieved in a number of ways. One method is open-flame annealing of cold-drawn rod—that is, heating to 700 °C (1300 °F) in an oxidizing atmosphere. This eliminates shallow discontinuities. A more common practice, especially for...
