Material Summary
310moln stainless steel grade is a fully austenitic stainless steel that does not have intermetallic phases such as intergranular carbide precipitations. For applications in urea plants 310MoLN steel grade has a specififically designed optimized chemical composition. To stabilize and strengthen the austenitic phase the nitrogen in the chemical composition helps. 310 MoLN, material gives excellent corrosion-resistance in urea carbamate environments such as high-pressure strippers. Among wrought austenitic stainless steels it has a fairly high base cost. And it has a fairly high embodied energy and a fairly low ductility.
