UNS S31254 Stainless Steel Sheet: The Ultimate Guide
When you choose to buy quality S31254 stainless steel sheet, there have some important points we need to know before we get started.
What are UNS S31254 Stainless Steel Sheets?
S31254 stainless steel sheet is an super austenitic stainless steel sheet.
Due to the high molybdenum content, it has extremely high resistance to pitting corrosion and crevice corrosion.
This grade of stainless steel sheet was developed and designed for containing halide application such as seawater.
This stainless steel also has good uniform corrosion resistance especially in acids containing halide. This steel is superior to ordinary stainless steel.
It has good resistance to pitting corrosion (PI≥40) and good stress corrosion resistance under the conditions of sea water application and low-speed erosion.
It is a substitute material for nickel based alloys sheets and titanium plates.
What’s more, it has better high temperature resistance and corrosion resistance, which is irreplaceable for 304 stainless steel sheet.
What are the applications that UNS S31254 Stainless Steel Sheets can be used?
Due to excellent high temperature resistance and stress corrosion resistance, quality grade 254 SMO® stainless steel sheet is widely used for below applications.
- Marine structures in marine environment, seawater desalination, mariculture, seawater heat exchange industry
- Thermal power generation flue gas desulfurization device, wastewater treatment equipment
- Nuclear power generation, comprehensive utilization of coal, power generation
- Oil refining, chemical equipment
- Salt making industry, soy sauce brewing industry
- Paper production industry, various bleaching devices
Features of UNS S31254 Stainless Steel Sheet
The main features include the following:
- Excellent resistance to pitting and crevice corrosion
- High resistance to general corrosion
- High resistance to stress corrosion cracking
- Higher strength than conventional austenitic stainless steels
- Good weldability
