304 stainless steel material:
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 resistance of 800 degrees, has the characteristics of good processing performance and high toughness, and is widely used in industrial and furniture decoration industries and food and medical industries.
Common labeling methods on the market include 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally means national standard production, generally means ASTM standard production, and SUS 304 means Japanese standard production.
304 is a general-purpose stainless steel, which is widely used to make equipment and parts that require good comprehensive properties (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 grade of stainless steel produced according to the American ASTM standard.
304 stainless steel product standard:
For 304 stainless steel, the ni element in its composition is very important, which directly determines the corrosion resistance of 304 stainless steel and its value.
The most important elements in 304 are Ni and Cr, but they are not limited to these two elements. Specific requirements are specified by product standards. The common judgment in the industry is that as long as the Ni content is greater than 8% and the 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. In fact, the relevant product standards have very clear regulations for 304, and these product standards have some differences for different shapes of stainless steel.
