Effect of tungsten on the oxidation of alumina-forming

Nov 14, 2019 · The oxidation-resistance of conventional austenitic stainless steels is obtained by the formation of chromia (Cr 2 O 3) layer as the protective surface scale. On the other hand, a considerable number of attempts have been made to substitute it with alumina (Al 2 O 3 ) as a way to improve oxidation-resistance (Ramakrishnan et al. 1988 ; Yamamoto Enhancing the Corrosion Resistance of Austenitic Steel Austenitic steels are very popular metallic materials used in the chemical, food, automotive, nuclear and medical industries, to name a few [ 1 ]. The corrosion resistance of austenitic alloys results from their high chromium content and the single-phase structure of paramagnetic austenite.

It replaces the conventional, austenitic stainless steels (AISI 316 and 317), where their capabilities are pushed to their performance limits. The alloy, therefore, falls into a super austenitic stainless steel category. It can also represent a cost-effective alternative to the higher nickel alloys in

Austenitic stainless steels have a austenitic, face centered cubic (fcc) crystal structure. Austenite is formed through the generous use of austenitizing elements such as nickel, manganese, and nitrogen. Austenitic stainless steels are effectively nonmagnetic in the annealed condition and can be hardened only by cold working.Austenitic stainless steel grades OutokumpuThe strength of austenitic steel grades is reinforced with increased levels of carbon, nitrogen and, to a certain extent, molybdenum.
