Material 1.4460

Duplex Superduplex

1.4460 is an austenitic ferritic stainless steel. It belongs to the group of superduplex steels. Its two phased microstructure combines the positive characteristics and ferritic stainless steels. These characteristics result in a high corrosion-resistance and high strength values. Often parts for valves and pumps are being produced out of 1.4460.The PREN-value of 1.4460 is ranged between 30,09 and 37,80 %. The PREN-value indicates the corrosion-resistance of a stainless steel. Starting at 32 % a steel is considered resistant against sea water. The PREN-value can be reached with the formula: %Cr + 3,3xMO + 16x%N
