OTMT Stainless Steel Tool Wraps for Perfect Heat-treated Tools. OTMT stainless steel tool wraps are a must-have when it comes to heat-treating your tools or machine parts. They are inexpensive and very easy to use. You just have to wrap your tool with this stainless steel tool wrap and crimp the edges of the wrap to make an envelope and to seal away air. These tough foils are perfect for both in-house and industrial heat-hardening of steel tools. You can cut, fold, and crease-seal the 321-type wraps with ease, and under normal use, the hand-made envelope does not get torn. This air-tight envelope will help retain the surface carbon during the heat-treating process, which in turn prevents your tool from getting damaged and scaled. Thus, after the heat treatment, you get your tools ready to use without any need for repairing or polishing. The 0.002-inch thick foils come in 50-feet and 100-feet rolls, with varying widths, such as 10, 20, and 24 inches so that you can choose as per your requirements. For Type 321 tool wraps, OTMT uses 321 annealed stainless steel, and they can be used in temperature levels up to 1800-degree Fahrenheit. All models in this set of heat treat foils come with a density of 8.00 g/cc, and their melting range is between 2250 and 2600-degree Fahrenheit. Moreover, they effectively replace the expensive box-package heating process where the tools are covered with either sawdust or charcoal. The wraps are supplied in a handy, resealable carton. Also, OTMT offers a tool wrap crimper tool and a tool wrap foil roller, which you can purchase if you need them.
