TP310MOLN/1.4466/S31050 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.
High-nickel austenitic stainless steel for parts and components of chemical apparatus used mainly in the production of urea. The grade is suitable for working at elevated temperatures. 1.4466 steel is used in the paper, nitrogen, pharmaceutical, petrochemical and cellulose industries.
