SAE-AISI M10 (T11310) Molybdenum High-Speed Steel

SAE-AISI M10 steel is a tool steel. M10 is the designation in both the SAE and AISI systems for this material. T11310 is the UNS number.

The properties of SAE-AISI M10 steel include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare SAE-AISI M10 steel to: tool steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
