PRODUCT DESCRIPTION

1.4466 UREA 25.22.2 310MoLN duplex steel S31050 bars and rods

 

 
Introduction
HT PIPE company supplies high quality 310MoLN bars.
Stainless steel grade 310MoLN is a fully austenitic stainless steel that does not have intermetallic phases such as intergranular carbide precipitations. The 310MoLN steel grade has an optimized chemical composition designed specifically for applications in urea plants. The nitrogen in the chemical composition helps to stabilize and strengthen the austenitic phase. This material provides improved corrosion-resistance in urea carbamate environments such as high-pressure strippers.
Density: 7.9g/cm3
 
Character
  • Very good corrosion resistance to carbamide synthesis.
  • Good corrosion resistance to intergranular corrosion.
 
Application
Production of carbamide.
