How 321 Thin Stainless Steel Foil Is Made?
- Cold rolling of 321 stainless steel foils: The cold rolling of stainless steel is to further reduce the thickness of the hot rolled steel sheet and make it into a thin strip foil. It is divided into continuous cold rolling and batch cold rolling.
- Annealing of 321 stainless steel foils: After cold rolling, the thin strip needs annealing to restore the mechanical properties lost during cold rolling.
- Slitting of 321 stainless steel foils: The annealed stainless steel strip is slitted according to requirements, and the width of the thin strip is determined by customer requirements.
- Packing and shipping of thin 321 thin stainless steel foils: After the slitting, the thin strips are packed in wooden cases to prevent damage during transportation and storage.

What is garde 321 thin stainless steel foil?
Grade 321 stainless steel foil is a stabilized austenitic stainless steel foils with good general corrosion resistance.
It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C).
The 321 foil resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than grade 304 stainless steel foil. It also possesses good low temperature toughness.
Grade 321 stainless steel foil can be easily welded and processed by standard shop fabrication practices; post-weld heat treatment is not required.
