High temperature resistant
254SMO stainless steel 9.53*1.24 coiled tube
1. Extensive field experiments and extensive experience have shown that even at slightly higher temperatures, 254SMO has a very high resistance to crevice-corrosion in seawater, which only a few types of stainless steel have.
2. 254SMO’s corrosion resistance in acidic and oxidizing halide solutions such as those required for paper bleaching production is comparable to that of the most resistant nickel-base and titanium alloys.
3. Because of its high nitrogen content, 254SMO has a higher mechanical strength than other kinds of austenitic stainless steel. In addition, 254SMO 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 at annealing, resulting in a rougher surface than ordinary stainless steel after pickling. But this has no adverse effect on the corrosion resistance of the steel.
