S31050 is a specialized stainless steel grade with enhanced corrosion resistance in urea environments, making it a valuable material for urea plant components. 

• Chemical Composition:

  The key elements in S31050 include Chromium (24-26%), Nickel (21-23%), Molybdenum (2-2.50%), and Nitrogen (0.10-0.16%). 
• Austenitic Structure:

  The alloy’s austenitic structure, stabilized by nitrogen, provides good mechanical properties and resistance to intergranular corrosion. 
• Corrosion Resistance:

  S31050 is particularly resistant to corrosion in urea carbamate environments, making it suitable for urea strippers and other high-pressure, corrosive applications. 
• Mechanical Properties:

  It exhibits good tensile and yield strength, as well as elongation at break, making it suitable for a range of applications. 
• Applications:

  S31050 is commonly used in urea plants, including urea strippers, pipes, and fittings. 
• Other Designations:

  S31050 is also known as 310MoLN, 1.4466, and UNS S31050.
