The grade CF8M refers to a specific type of stainless steel used in valve manufacturing, particularly in the investment casting process. It is an alloy composed primarily of 18% chromium and 8% nickel, with the addition of molybdenum, which enhances its corrosion resistance and strength at elevated temperatures. This grade is commonly used in applications involving corrosive environments, such as chemical processing and marine industries, due to its excellent resistance to pitting and crevice corrosion.
cf8m is a Sharpe Valve model # , 1000 CWP means it is rated for 1000psi Constant Working Pressure
8.9E10-6 in/inF at 70-212F
It means that the material of the Valve has been up to the ASTM Casting Specification ASTM A351 Grade CF8. Used for corrosive or extremely high temperature Non Corrosive services.
Stainless Steel version
CF8M is a low-carbon version of CF8, which are both types of stainless steel. CF8M has a higher chromium and nickel content, making it more corrosion resistant than CF8. CF8 is often used in applications where corrosion resistance is less critical compared to CF8M.
