**321 Tri-Ply Stainless Steel Disc**

This 321 tri-ply stainless steel disc is an upgraded cookware material based on the standard tri-ply structure. Instead of using 304 stainless steel as the inner food-contact layer, it uses **321 stainless steel**, which contains a small amount of titanium.

The key reason for choosing 321 stainless steel is its titanium content. Titanium is a stable element and is not easy to react with other elements. Because of this, cookware materials containing titanium are often viewed as a healthier and more premium option by many customers.

The disc keeps the classic tri-ply structure: **321 stainless steel on the inside, aluminum in the middle, and magnetic stainless steel on the outside**. The inner 321 stainless steel layer provides a durable and hygienic cooking surface, the aluminum core helps distribute heat quickly and evenly, and the outer magnetic stainless steel layer makes the cookware suitable for induction cookers and other heat sources.

This 321 tri-ply stainless steel disc is suitable for cookware manufacturers who want to develop titanium-enhanced stainless steel cookware, premium pots, frying pans, saucepans, and other high-value kitchenware products. It combines the advantages of tri-ply heat performance with the marketing appeal of titanium-containing stainless steel.
