Abstract In order to develop the Fe-Cr-Ni-Mo-Mn-N corrosion resistant alloys, analyze the influence of nitrogen on the corrosion resistance of Fe-Cr-Ni-Mo-Mn alloy, adjust the N content in the alloy system, and Flux cored wires with different N content were prepared. They were surfaced on low carbon steel by MIG welding. The phase composition, microstructure and corrosion resistance of the cladding metal were analyzed to studied the effect of N content on the structure and performance of the surfacing metal. The results show that the addition of nitrogen does not change the matrix structure (which is Fe-Ni-Cr austenite), but with the increase of nitrogen content, the precipitation of nitrides （ Cr2(C,N) and BN ） is

In order to compare the corrosion resistance of conventional low carbon steel, Cu containing low carbon steel for sulfuric acid dew-point corrosion inhibition, and stainless 409L, immersion tests were carried out in 50 wt.% sulfuric acid. The effects of HCl concentraion on the corrosion behavior in a fixed sulfuric acid concentration (16.9 vol.%) was also investigated by immersion test. In addition to immersion test, field test in a thermal plant was carried out for 10 months. As a result, it was confirmed that Cu-containing dew-point corrosion resistent steel has the highest corrosion resistance compared with other materials. To verify superior corrosion resistence of dew-point corrosion resistant steel, surface morpology after various test was observed by SEM. It was found that surface corroded product of the dew-point corrosion resistant steel was much denser and thicker compared with the other steel.

The Ideal

The larger variation of the construction and performance of the low-carbon steel joints was caused by the high temperature of the puddle welding of the joint. Therefore, the braze welding rather than the puddle welding was applied to the welding production of low-carbon steel. The 08 steel parts were joined in a furnace using pure copper solder paste as brazing filler metal. According to the obtained results, the ideal technical parameters are as follow: brazing temperature: 1100-1150°C; holding time: 5-10min; joint clearance: 0.03-0.05mm.

Corrosion-resistant metals and alloys towards liquid metals determine the service performances and lifetime of the devices employing liquid metals. This paper studies the static corrosion behaviors of iron, chromium, nickel, low carbon steel, and four types of stainless steels (SS410, SS430, SS304, SS316L) in liquid Sb-Sn at 500 oC, aiming to screen corrosion-resistant SS for Li||Sb-Sn liquid metal batteries (LMBs). The corrosion rates of Fe and Ni are 0.94 μm h-1 and 6.03 μm h-1 after 160 h’s measurement, respectively. Cr shows a low corrosion rate of < 0.05μm h-1, which is due to the formation of a relatively stable Cr-Sb layer that may be able to prevent the interdiffusion between the solid substrate and liquid Sb-Sn. Ni has a high corrosion rate because the formed Ni-Sb and Ni-Sn compounds are soluble in the liquid Sb-Sn. The corrosion products of both pure metals and SS can be predicted by thermodynamic and phase diagram analysis. Among the four types of SS, SS430 shows the best corrosion resistance towards liquid Sb-Sb with a corrosion rate of 0.19 μm h-1. Therefore, a liquid Sb-Sn resistant material should have a high Cr content and a low Ni content, and this principle is applicable to design metallic materials not only for LMBs but also for other devices employing liquid Sb- and Sn-containing liquid metals.

Increase Corrosion Resistance

The purpose of the work was to identify and analyze the causes of corrosion destruction of metal products, used in conditions of animal keeping on farms of the agro-industrial complex, and to find effective methods of combating it. In order to increase corrosion resistance of metal products of livestock farms and complexes, it is proposed to use the developed preparation, which has fungicidal and anticorrosive properties simultaneously. The rate of metal products corrosion during the experiment was evaluated by the museum strain of Aspergillus niger fungi. The article describes the causes of fungal corrosion, the principle of its effect on metals; proposes an inhibitor of complex action for the control of electrochemical and bio-corrosion. The protection efficiency of metal products by the inhibitor was evaluated by the corrosion braking coefficient and the degree of protection. The effect of inhibitor concentration on the rate of low carbon steel bio-corrosion has been studied. It has been proven that the rate of corrosion processes decreased by 50 times, when exposed to a medium, contaminated with fungus spores, on metal samples treated with an inhibitor.
