1. A large number of field experiments and extensive use experience show that even at slightly higher temperatures, 254SMO has high crevice corrosion resistance in seawater, and only a few types of stainless steel have this performance.

2. The corrosion resistance of 254SMO in acidic solutions and oxidizing halide solutions required for paper bleaching production is comparable to nickel-based alloys and titanium alloys with the strongest corrosion resistance.

3. Because 254SMO has a higher nitrogen content, its mechanical strength is higher than other types of austenitic stainless steel. In addition, 254SMO also has high ductility and impact strength as well as good weldability.

4. The high molybdenum content of 254SMO enables it to have a higher oxidation rate during annealing, so that it has a rougher surface than ordinary stainless steel after pickling. But this has no adverse effect on the corrosion resistance of the steel.
