Abstract
Stainless steel 17-4 PH, also known as ASTM 630 or UNS S17400, is a low-carbon martensitic alloy widely used in the aerospace, aeronautical, marine, automotive, and nuclear sectors due to its combination of high corrosion resistance, high yield strength, and good ductility. This alloy is particularly suitable for additive manufacturing (AM) processes, making it one of the most commonly us…
