304 stainless steel (also known as 18/8 stainless steel in the industry) is a common stainless steel material with a density of 7.93 g/cm3 and a high temperature resistance of 800 ℃. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain at least 18% chromium and at least 8% nickel.
It has the characteristics of good processing performance and high toughness, and is widely used in the industrial and furniture decoration industry, food and medical industry, as well as in the production of equipment and parts that require good comprehensive performance (corrosion resistance and formability).
