What is Knufoil?

KNUFOIL is a special stainless steel alloy foil, manufactured by the Knight Group, commonly used for tool wrap applications.  

What is Stainless Steel Tool Wrap?

Our Stainless Steel Tool Wrap provides a quick and low cost method of protecting the surface of tools, dies and other parts during the hardening process by preventing decarburization (scaling). Protecting the surface of your tools is achieved simply by using KNUFOIL to create protective foil envelopes. These stainless steel tool wrap envelopes lock out the air and as a result, eliminate the need for expensive protective atmosphere furnaces. Furthermore, this process only increases hardening time by two or three minutes.

A further major advantage is an option to use a faster quenching medium – for example, using water rather than oil. This is due to the insulating effect of KNUFOIL in the quenching medium, which is sufficient to reduce the risk of cracking, which is normally the result of using a faster quench. Equally, it eliminates the need for encapsulating or coating the product in a protective material, which might be difficult to remove after hardening. By using our Tool Wrap, manufacturers have a low cost alternative to expensive protective atmosphere furnaces.
