The latest technical case study to be published by LPW Technology Ltd, Runcorn, UK, is now available for free download from the company’s website. The article, ‘Maraging Steel: The effects of alloy chemistry on processability’, discusses a particular case of micro-cracking within parts that occurred when using a maraging steel powder.
“A metal powder can not only move out of, but can also vary within, specification,” stated Dr Rob Deffley, LPW’s Research & Development Manager. “In this particular case study, we follow the analysis of batches of M300 maraging steel as our highly skilled applications engineers identify the issues that led to a problem with the final mechanical properties of a built part. We also explore the solution they designed to resolve the problem.”
‘Maraging Steel: The effects of alloy chemistry on processability’ can be found in the LPW website technical library, alongside the brochures and the laboratory services datasheets. These resources are all free to download.
