How to calculate the processing fee of 304 stainless steel plate?
304 stainless steel is a common material in stainless steel with a density of 7.93 g/cm3. It is also called 18/8 stainless steel in the industry. It is resistant to high temperatures of 800 degrees and has the characteristics of good processing performance and high toughness. It is widely used in industry, furniture decoration industry, food and medical industry.
Common marking methods on the market include 0Cr18Ni9 and SUS304, among which 0Cr19Ni10 generally indicates production according to national standards, S30408 generally indicates production according to ASTM standards, and SUS 304 indicates production according to Japanese standards.
304 is a versatile stainless steel that 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 brand of stainless steel produced in accordance with American ASTM standards.
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. A 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 a 304 stainless steel plate. 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 on 304, and these product standards have some differences for different shapes of stainless steel. Below are some common product standards and tests.
