    STAINLESS STEEL FOIL ALLOY 321. Stainless Steel Foil Alloy 321 is an electric-furnace processed austenitic stainless steel. It is not heat treatable and non-magnetic in the annealed state. It contains 18% chromium, 8% nickel, and a substantial addition of titanium.

  2. Aug 11, 2020 · Stainless Steel Tool Wrap is typically .002” thick type 309 or Type 321 Stainless Steel foil used to wrap metal tools, dies, and other parts during high-temperature heat-treating to achieve a hardened temper. The part to be heat-treated is placed in an envelope formed by folding a foil sheet in half and sealing the.

  3. Aug 12, 2005 · tmickley. 309 and 321 foil temp rating depends on who makes it. 321 can usually handle up to 1800F to 1950F (again, depending on who makes it) but prefers tool steel range in the 1500's. I probably wouldn't use any 321 at 1975F since it gets pretty crunchy at that range.

  4. Jun 24, 2021 · Select type based on heat treatment temperature: Type 321 Stainless Steel is used in temperatures up to 2000° F. Type 309 Stainless Steel will work in temperatures up to 2240° F. Cut to size: Tool Wrap is made out of a material that can easily and quickly be cut with snips or heavy scissors.

  7. Reinforced with titanium, 321 stainless steel excels in high temperature environments, providing resistance to cracking and corrosion. Additionally, 321 stainless resists scaling at higher temperatures. The addition of titanium means that welding is not suggested for this alloy.

  8. Type 321 is a stabilized austenitic stainless steel similar to type 304 but with a titanium addition. This titanium addition reduces or prevents carbide precipitation during welding and in 800 - 1500 °F (427 - 816 °C) service. It also improves the elevated temperature properties of the alloy.
