🔹 About DIN 1.4465

DIN 1.4465, also designated as X1CrNiMoN25-25-2, is a high-alloy austenitic stainless steel with added molybdenum and nitrogen. It is similar to DIN 1.4466 (AISI 310MoLN) but with slightly higher nickel content. The grade is known for outstanding corrosion resistance, particularly in sulfuric, phosphoric, and chloride-rich environments, as well as good performance at elevated temperatures.
