Working with A2 Tool Steel

A2 Tool Steel can be heat treated to increase hardness and durability. Markforged recommends heat treating A2 Tool Steel to optimize material properties, though it can be used as-sintered. Heat A2 Tool Steel part in a standard (non-vacuum) furnace to 970°C (1780°F). Hold part at temperature for 30-45 minutes. Air quench part to below 65°C (150 °F). Double temper A2 Tool Steel part in a standard furnace. For each temper, heat part to 150-550°C (302-1022°F) and temper for 2 hours, or 1 hour per inch of thickness. Let part cool to room temperature between tempers.


Compatible with our Metal X system.
