304 stainless steel is a common material in stainless steel, with a density of 7.93 g / cm3, also known as 18 / 8 stainless steel in the industry.

High temperature resistant 800 ℃, with good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.

304 is a kind of universal stainless steel, which is widely used in the production of equipment and parts requiring good comprehensive performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a brand of stainless steel produced according to American ASTM standard.

For 304 stainless steel, the Ni element in its composition is very important, which directly determines the corrosion resistance and value of 304 stainless steel.

The most important elements in 304 are Ni and Cr, but they are not limited to these two elements.

The specific requirements are stipulated by the product standard. Industry common judgment that as long as the Ni content is greater than 8%, Cr content is greater than 18%, it can be considered as 304 stainless steel.

This is why the industry calls this type of stainless steel 18 / 8 stainless steel.

304 stainless steel is food grade stainless steel approved by the nation.
