What is CF8 Stainless Steel ?
CF8 is equivalent to Chinese model zg0cr18ni9, corresponding to 304 stainless steel
It is austenitic stainless steel, which is used as stainless steel heat-resistant steel. Food equipment, general equipment, and atomic energy industrial equipment.
This kind of alloy is the most common steel. It has good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties. 304 stainless steel has good workability at room temperature and will not harden after heat treatment.

304 stainless steel
304 stainless steel is a common material in stainless steel, the density is 7.93 g / cm3, also known as 18 / 8 stainless steel in the industry. It is used in industry, furniture decoration industry, and food and medical industry.
06cr19ni10 and SUS304 are the common marking methods on the market, among which 06cr19ni10 generally refers to national standard production, 304 generally refers to ASTM standard production, and SUS 304 refers to Japanese standard production.
304 is a kind of universal stainless steel, which is used to make equipment and parts with good comprehensive performance (corrosion resistance and formability). 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 the American ASTM standard.
What is the difference between 304 vs 316 stainless steel ?
In short, the difference between 304 vs 316 stainless steel is mainly reflected in price and corrosion resistance. If you want to apply in a high corrosive environment, 316 stainless steel can greatly increase the service life. If not, 304 stainless steel can be used.
