Markforged 3D Printed A2 Tool Steel, Heat-Treated
Categories:	Metal; 3D Printing/Additive Manufacturing Metal; Ferrous Metal; Tool Steel; Air-Hardening Steel
Material Notes:	A2 tool steel is a highly versatile air-hardening tool steel often regarded as a “universal” cold work steel. It offers a combination of good wear resistance (between O1 and D2) and toughness. Considered relatively easy to machine in the annealed condition, it has a high compression strength and good dimensional stability during hardening and tempering. It’s used for a wide variety of cold-work tools, from forming and cutting equipment to high wear parts. Information provided by Markforged, Inc.
