Researchers Share 3D-Printing of 17-4 PH Stainless Steels


A microscopic image of 3D-printed 17-4 stainless steel. The colors in the left-side version of the image represent the differing orientations of crystals within the alloy. 

For airliners, cargo ships, nuclear power plants and other critical technologies, strength and durability are essential. Therefore, many contain a remarkably strong and corrosion-resistant alloy called 17-4 precipitation hardening (PH) stainless steel. A team of researchers from the National Institute of Standards and Technology (NIST), the University of Wisconsin-Madison and Argonne National Laboratory has identified particular 17-4 steel compositions that, when printed, match the properties of the conventionally manufactured version. The researchers’ strategy is based on high-speed data about the printing process they obtained using high-energy X-rays from a particle accelerator.
