254SMO Stainless Steel Sheet

254SMO Stainless Steel Sheet has excellent corrosion resistance, especially in harsh environments such as seawater and chloride-containing solutions. 6MO Plate also has high tensile strength and yield strength, and in most cases, its mechanical properties are almost twice that of 300 series steel. ASTM A240 UNS S31254 Plate can even be used as a substitute for high nickel titanium alloys due to its low cost compared to titanium alloys. We are a SS 254SMO supplier with 15+ export experience, contact us for more information and free quotes!

SS 254SMO Annealing Process

Annealing should be carried out at 1149-1204°C, followed by water quenching.

 

6MO UNS S31254 Plate Test

• Tensile strength, yield strength, elongation, hardness test
• Flattening
• Bending
• Impact test
• Chemical composition test
• Non-destructive testing
• Hydraulic pressure test

 

Recognized 254 SMO Plate, Sheet or Foil 

• If the thickness is greater than 6.35 mm, it is called a plate.
• If the thickness is greater than 0.15 mm and less than 6.35 mm, it is called a sheet.
• If the thickness is less than 0.15 mm, it is called foil.
