In the national standard of stainless steel products for food safety in China, stainless steel can be used to make tableware, but it needs to pass the test and obtain the production license.
304 stainless steel (high nickel stainless steel) is widely used in tableware making because of its strong rust resistance.
200 series stainless steel products are not qualified for tableware in China. 20 1 stainless steel is hard, rigid and easy to crack, but its characteristics of acid and alkali resistance, high density, polishing without bubbles and pinholes make it a high-quality material for making various watchcases and watchbands.
20 1 stainless steel is mainly used for decorative pipes, industrial pipelines and some shallow tensile products. 20 1 stainless steel has poor antirust performance and is generally used for products with dry contact environment.
