On the influence of cold work on the oxidation behavior of some austenitic stainless steels: High temperature oxidation [PDF]

open access: yes, 1984
AISI 304, 314, 321, and Incoloy 800H have been subjected to several pretreatments: polishing, milling, grinding, and cold drawing. In the temperature range 800–1400 K, cold work improves the oxidation resistance of AISI 304 and 321 slightly, but has a ...
