1.4547 – X1CrNiMoCuN20-18-7 – 254 SMO – UNS S31254

Highly alloyed austenitic stainless steel. Excellent corrosion resistance, good mechanical characteristics and good welding ability, it is mainly used for equipment used in marine and other aggressive environments containing chlorides, annealing should be carried out at around 1150°C and followed by water cooling, we can work harden it to increase the mechanical properties.
