heat treating with stainless steel bag

Jun 07, 2013We do our own heat treating also. We buy the stainless steel wrap to cover parts when heat treating. Most of the steel is air hardening so the time to open the bag is no so much of an issue. What I so is use some tongs to hold the bag and a tin snip to cut it open, works for me.

Why Does Stainless Steel Rust? Polymer Solutions

A less common form of rusting in stainless steel is after the stainless has been exposed to very high temperatures, often in the 750-1550F range (400-850C) 1. This type of corrosion is often seen in welding applications in which stainless is heated and then cooled.
