SAE-AISI F2 (T60602) Low-Alloy Tool Steel

SAE-AISI F2 steel is a tool steel. F2 is the designation in both the SAE and AISI systems for this material. T60602 is the UNS number.

The properties of SAE-AISI F2 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 F2 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.
