Characteristics of stainless steel circle

High Strength

Stainless steel circles have relatively high tensile strength and impact resistance. This makes them excellent in applications where support and load-bearing functions are required.

Corrosion Resistance

Stainless steel circle contains a high proportion of chromium, forming a layer of dense chromium oxide film to prevent oxygen and water from contacting the stainless steel, thus providing strong corrosion resistance.

Sanitation

The surface of the stainless steel circle is smooth, without pores or cracks, and it is not easy to breed bacteria.

Machinability

Stainless steel circles can be easily cut, punched, welded and machined into desired shapes and sizes.
