NanoSteel has used laser sintering to turn its nanostructured steel powders into high-hardness metallic parts that do not crack during the build process. Working with a process development partner, the company says it was able to produce a fully dense, crack-free part with hardness values exceeding 1,000 HV, wear resistance comparable to conventionally manufactured M2 tool steels and a uniform microstructure. In addition, these properties were achieved without the need for post-processing such as hot isostatic pressing or further heat treatment, reducing production cost and lead times.
