This will likely create an air-tight package which will prevent the lack of surface carbon right through heat treating. The usage of stainless steel tool wrap not only protects your tooling from expensive repairs, it also removes the need for box packaging with charcoal or sawdust.
Used when heat treating tooling.
The tooling is wrapped within the foil with the edges crimped to form an envelope.
The lack of surface carbon causes the tooling to grow to be scaled and damaged.
