  • UNS S31050
  • UREA 25.22.2
  • 310MoLN
 
 
 

UREA 25.22.2 chemical composition has been optimised for specific uses in Urea plants. It is a 310L modified austenitic stainless steel with low carbon, low
silicon and high nitrogen additions in order to stabilize and strengthen the austenitic phase. The alloy is particularly designed for improved corrosion resistance properties in urea carbonate environments including strippers. The grade is also well designed for resistance in wet corrosive conditions due to its high contents of chromium, molybdenum and nitrogen (PREN > 33). UREA 25.22.2 is designed for the fabrication of lining interiors in Urea units or complementary products (pipes, fittings…). The grade can be used for urea strippers.

 
 
 
 

Mechanical Properties

Tensile strength: 540-740 N/mm²
Yield strength 0,2% : 250 ≥ N/mm²
Elongation: 35/30 ≥ %
Hardness Brinell: 240 ≤ HB
 

Chemical Composition

The chemical composition of stainless steel grade 310 MoLN is outlined in the following table.

Element Content (%)
Iron, Fe Balance
Chromium, Cr 24-26
Nickel, Ni 21-23
Molybdenum, Mo 2-2.50
Manganese, Mn ≤ 2
Nitrogen, N 0.10-0.16
Silicon, Si ≤ 0.70
Phosphorous, P 0.025
Carbon, C ≤ 0.020
Sulfur, S ≤ 0.010
 

Heat Treatment

heat treatment (1140°-1180°C –2084-2156°F) and water quenching

 
 

The corrosion resistance properties are enhanced thanks to the low carbon level, low silicon level and complementary additions of nitrogen.

Typical maximum corrosion results required following different specifications for the 25.22.2 grade after 5 periods of 48 h following ASTM A 262-C practice are:
maximum general corrosion: 1,6 μm/48 h or 65 mg/dm² per hour with a maximum depth of microcracks of 100 μm in the long direction of rolling.

 

Marking

All material will be marked as follow:

  • Manufacturer’s name
  • Material grade
  • Size
  • Heat Number
 

Certification

Material will be delivered with certificate EN 10204 3.1
