Cookware: 304 (06Cr19Ni10) is mostly used; for products with composite bottoms, pay attention to the matching of the aluminum/copper composite layer with the steel grade.

Tableware: 304 is predominant; 430 (10Cr17) can be used for low-cost knives and forks, but its corrosion resistance is weaker.

Sinks: 304 is common; 316L is recommended for coastal or high-salt environments; sinks with large drawing depths require suitable material elongation and grain size.

Surface: brushed (No.4) is wear-resistant; mirror (8K) is aesthetically pleasing but easily scratched; the inner surface can be electropolished to improve cleanability.

Note: Food-contact materials must comply with the GB 4806 series or FDA requirements.
