Precision Brand® Type 309 Tool Wrap provides superior protection against scale and oxide buildup during heat treatment in atmospheric furnaces.

Made from soft annealed Type 309 stainless steel, this high-performance wrap prevents decarburization and resists chromium carbide precipitation at extreme temperatures—up to 2240°F.

Designed for use with air-hardening tool steels, it creates an airtight envelope around parts, ensuring a clean surface finish.

Easy to cut, fold, and crease-seal, it offers the benefits of a vacuum furnace at a fraction of the cost. Packaged in a convenient, reclosable carton for easy storage and handling.
