An air-hardening tool steel built for making tools and tooling, not end-use parts.
An air-hardening tool steel built for the tools that make other parts, not for the parts themselves.
High compressive strength, excellent dimensional stability through heat treatment, and strong wear resistance once hardened.
When you're building tooling — dies, punches, fixtures, gauges — rather than an end-use part.
Stamping dies, punches, tool holders, gauges, fixtures.
Typically machined before heat treatment (softer, easier to cut), then hardened afterward — sequencing matters for this material. Once it is hardened to C57-C62, any feature that needs tighter tolerance or a better surface finish than milling can hold is finished by precision grinding.
