Tool Steel for the Automotive Industry
Tool steel plays a critical role in automotive manufacturing due to its strength, durability, and resistance to wear. It's commonly used to produce dies, molds, cutting tools, stamping tools, and other components that must withstand extreme pressure and temperature variations during vehicle assembly.
At Southern Tool Steel, we carry an extensive inventory of tool steel grades tailored to automotive applications, including:
- A2 Tool Steel: Air-hardening with good dimensional stability, a common choice for blanking and piercing dies used in sheet metal body panel production.
- D2 Tool Steel: High carbon and chromium content for exceptional wear resistance, well suited for long-run progressive dies and trim tooling where abrasive wear from galvanized or high-strength steel sheet is a concern.
- H13 Tool Steel: Excellent hot hardness and toughness, widely used for die casting dies and extrusion tooling in aluminum component and engine part production.
- S7 Tool Steel: Shock-resistant and versatile, often selected for punches, pilots, and forming tools that see repeated impact in high-speed stamping presses.
- O1 Tool Steel: Oil-hardening and easy to machine, a practical option for lower-volume die work, gauge blocks, and prototype tooling during vehicle development.
Our tool steels are available in flat bar, round bar, and plate, and we can cut materials to your die or tooling specifications.
