EN 1.4466, also known as AISI 310MoLN or S31050, is a stainless steel with excellent resistance to intergranular corrosion, pitting corrosion and crevice corrosion. In addition, it has good resistance to high temperature and high pressure, making stainless steel EN 1.4466 the preferred material for Urea Solution (Ammonium Carbamide Solution).
