UNS N08034, commonly referred to as Alloy 31 Plus(1), is a non-precipitation-hardenable super austenitic stainless steel that is currently commercially available in the solution-annealed state. Compared to its predecessor, Alloy 31(2) (UNS N08031), it has an increased nickel content and the addition of nitrogen and manganese, which serve to stabilize the austenitic phase. The well-balanced chemical composition of UNS N08034 enables excellent machinability in both hot and cold conditions, as well as favorable weldability. In the oil and gas industry, materials selected for various applications must possess superior corrosion resistance and enhanced mechanical strength, particularly at the expected operating temperatures. UNS N08034 shows promising potential for exploration in this regard. However, to meet the application requirements, an alternative production route must be established, specifically focusing on mechanical strength. This paper presents two distinct approaches. Firstly, the development of a cold working processing route for UNS N08034 is discussed. Secondly, the influence of specific alloying elements on the response to cold work is examined.

Testing is performed in seawater cooled scale model heat exchangers with 0.5 ppm residual chlorine during a period of 18 months. Thus, it shows a corrosion resistance of the materials at a heat flux representative to a tube skin temperature up to 95°C inside in the seawater.
