New Case-Hardening Steel Designed for Laser Powder Bed Fusion

Printed Industrial Die Demonstrates Performance of the BLDRmetal™ L-40 Powder

PROVIDENCE, R.I. (Monday, June 19, 2017)—NanoSteel®, the leader in nanostructured steel materials, today announced the launch of its first product for the laser powder bed fusion additive manufacturing process. BLDRmetal™ L-40 is a case-hardening steel powder that provides high hardness and ductility (case hardness >70HRC, 10%+ core elongation) and prints easily on standard commercial equipment. This alloy provides superior performance to M300 maraging steel and is an alternative to difficult-to-print tool steels such as H13. Expanding the potential use of 3D printing in a wide variety of hard materials markets, BLDRmetal™ L-40 is designed to be used for parts including tools, dies, bearings and gears.

The capabilities of BLDRmetal™ L-40 were demonstrated by printing an 8-inch roll thread die set, which outperformed dies machined from D2 and M2 tool steels. “We tried nearly every combination of material and conventional CNC machining process to create our dual-thread die sets, none of which could cut or grind the complicated dual-thread geometry,” said Mark Doll, President and CEO of Perfect Lock Bolt America Inc., the only manufacturer of dual-thread fasteners in North America that are resistant to self-loosening. “The NanoSteel solution delivers exactly what we are looking for, including excellent surface finish, flexibility, as well as strength and hardness for maximum die life. This is a welcomed technological innovation to the fastener industry. We have been pleased with our testing and are slated to start production this year.”
