Tool steel S7 is a type of shock-resistant and air-hardening steel. It is commonly used in the manufacturing of tools and dies due to its ability to withstand high impact and retain its hardness at high temperatures. S7 tool steel is also resistant to wear and abrasion, making it well-suited for use in demanding applications. It is often used in the aerospace, automotive, and construction industries.
