  1. what is the ss Grade 310 MoLn (UNS S31050)

    Stainless steel grade 310 MoLN 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.

2.Chemical Composition

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