Pitting Corrosion Resistance

Pitting corrosion resistance and intergranular corrosion of the austenitic stainless steel X5Cr Ni18-10 were tested on the base metal, heat affected zone and weld metal. Testing of pitting corrosion was performed by the potentiodynamic polarization method, while testing of intergranular corrosion was performed by the method of electrochemical potentiokinetic reactivation with double loop. The base metal was completely resistant to intergranular corrosion, while the heat affected zone showed a slight susceptibility to intergranular corrosion. Indicators of pitting corrosion resistance for the weld metal and the base metal were very similar, but their values are significantly higher than the values for the heat affected zone. This was caused by reduction of the chromium concentration in the grain boundary areas in the heat affected zone, even though the carbon content in the examined stainless steel is low (0.04 wt. % C).

Super Austenitic Stainless Steel

Abstract CarTech 25Ni-20Cr-6Mo is an extra low-carbon, 25Ni-20Cr-6Mo, super-austenitic stainless steel that is designed to resist pitting and crevice corrosion in acidic or neutral chloride environments. This resistance is provided by its chromium, molybdenum, and nitrogen content, while nickel stabilizes the austenitic structure. Nickel, in combination with copper, also provides resistance to some acid environments. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-1325. Producer or Source: Carpenter Technology Corporation.

Super Austenitic Stainless Steel

Stainless steels have significant applications due to their good corrosion resistance. However, for applications in a marine environment, i.e. for certain types of large naval structures, in addition to the good corrosion resistance, other requirements are imposed on the candidate material such as high strength and toughness coupled with suitable magnetic characteristics.It has been demonstrated in earlier publications that significant improvements in the coercivity, maximum induction and remanence values can be achieved, by using a 2205 type Duplex austenitic -ferritic stainless steel (DSS) instead of the low alloy medium carbon steels currently being used. These improvements are achieved in the as received 2205 material, and after small amounts of cold rolling have been applied, to increase the strength. However, the 2205 type DSS exhibits “ marginal” corrosion protection in a marine environment as well as exhibiting some measurable ferromagnetic response. Therefore, a study has been undertaken to examine the mechanical properties and microstructures obtained in a super austenitic stainless steel of the 254 SMO type.
