Precision Brand 20110 Type 321 Stainless Steel Tool Wrap

Product Description

The PRECISION BRAND 20110 is a Type 321 stainless steel tool wrap supplied in a 50-foot roll measuring 24 inches wide and 0.002 inches thick. Tool wrap foil is used to encase tooling, dies, and metal parts during heat treatment to control the atmosphere around the workpiece, limiting oxidation and decarburization at elevated temperatures. Type 321 stainless is a titanium-stabilized alloy that resists sensitization during prolonged high-heat exposure, making it the correct choice when standard Type 302 or 304 wrap would degrade prematurely. At 9.25 pounds per roll, this is a full production-grade quantity suited for shop use rather than single-part repair work.

This tool wrap is used in heat-treat ovens and furnaces in tool-and-die shops, manufacturing facilities, and metalworking operations. It is applied by wrapping parts or tooling tightly before placing them into the oven, creating a semi-sealed envelope that slows oxygen contact during hardening, annealing, or stress-relieving cycles. The 24-inch width accommodates a wide range of part sizes, and the 50-foot roll length provides sufficient material for multiple heat-treat runs before replacement is needed.

Key Features

• Type 321 titanium-stabilized stainless steel resists high-temperature sensitization
• 0.002-inch thickness provides a flexible, conformable wrap that seals closely around irregular part shapes
• 24-inch width handles a broad range of tooling and workpiece dimensions
• 50-foot roll length supports multiple heat-treat cycles per roll
• Single-piece roll format minimizes handling and allows cutting to any required length on the job

Compatibility

Designed for use as atmosphere-control wrap in heat-treatment applications requiring Type 321 stainless foil, compatible with standard heat-treat ovens and furnaces used in tool-and-die and metalworking operations.

Installation Notes

Tool wrap is applied by metalworkers and heat-treat technicians following the equipment manufacturer's cycle specifications. Ensure the oven or furnace is fully cooled and de-energized before loading or unloading wrapped parts. Use appropriate high-temperature gloves and tongs when handling parts after heat-treat cycles. Follow your facility's established heat-treatment procedures and applicable safety standards when operating high-temperature equipment.
