Air-hardening, cold-work tool steel exhibits impressive impact toughness and moderate wear resistance. Characterized by good dimensional stability during heat treatment, this specific alloy composition allows for intricate tool designs with minimal distortion. An example application would be long-lasting punches and dies used for high-volume production.
The balance of toughness and wear resistance offered by this type of tool steel makes it highly desirable for applications requiring both durability and the ability to withstand shock loading. Historically, its development arose from the need for tooling materials capable of performing reliably under increasingly demanding industrial conditions. This particular steel’s ability to be air-hardened simplifies heat treatment and reduces the risk of cracking compared to oil or water quenching methods, contributing to lower manufacturing costs and improved tool lifespan.
