m4p type62-DX can be classified as a duplex stainless steel and thus combines the advantages of two microstructures (austenite and ferrite): outstanding mechanical strength properties and excellent corrosion resistance. m4p™ Fe-type62-DX achieves PREN values (as a measure of pitting resistance) >32-39. For an optimum of material performance it is important to re-adjust the austenite-ferrite ratio after the L-PBF process with a heat-treatment (solution annealing + quenching).
