Wholesale price for 254SMO stainless steel round bar, factory-recommended 254SMO steel rod supplier
Shanghai Guoshuo Company produces 254SMO, an austenitic stainless steel. Due to its high molybdenum content, it boasts excellent resistance to pitting and crevice corrosion. This grade of stainless steel is developed and designed for use in environments containing halides, such as seawater. 254SMO also exhibits good resistance to general corrosion. Particularly in halide-containing acids, this steel outperforms regular stainless steels. With a carbon content of <0.03%, it is classified as a pure austenitic stainless steel (with <0.01% carbon, it's referred to as super-austenitic stainless steel).

In various acidic environments, the corrosion resistance of 254SMO stainless steel bars varies. Below, Shanghai Gushuo introduces this to you!
In pure sulfuric acid, 254SMO exhibits significantly greater corrosion resistance compared to 316 standard grade stainless steel.
At higher concentrations, the corrosion resistance of 254SMO is slightly weaker compared to 904L (NO8904) stainless steel.
In sulfuric acid containing chloride ions, the 254SMO exhibits corrosion resistance.
Due to potential localized and uniform corrosion, 316 standard grade stainless steel is not suitable for use in hydrochloric acid, but 254SMO can be used in diluted hydrochloric acid at normal temperatures.
Below the boundary line, there's no need to worry about point corrosion. However, it's crucial to avoid the presence of gaps.
In hydrofluorosilicic acid (H2SiF4), the corrosion resistance range of ordinary stainless steel is very limited, whereas 254SMO can be applied over a wide range of concentrations and temperatures.
