it is upto the composite of the alloys...cf8 doesnt contains molybdenum......cf8m contains molybdenum in the range of 2-3%...molybdenum provides high corrosion resistant to chlorides...
The force between two charges is inversely proportional to the square of the distance between them. This means that as the distance between the charges decreases, the force between them increases, and vice versa.
The distance between objects and the different is 0. The distance between the mass and an object is 1.
The force of gravity between two objects will increase if their distances decrease. The force of gravity or proportional to the objects' masses, and inversely proportional to the square of the distance between them.
A contrast between what is expected and what happens is called irony. Irony involves discrepancies between what is said and what is meant, or between what is expected and what actually occurs.
The force of gravity between two objects depends on their masses and the distance between them. The greater the mass of the objects and the closer they are, the stronger the force of gravity between them.
CF8M and CF8 are both grades of stainless steel, primarily used in casting. The main difference lies in their chemical composition; CF8M contains a higher percentage of molybdenum, which enhances its corrosion resistance, especially against chlorides. CF8, on the other hand, has a lower molybdenum content and is typically less resistant to pitting and crevice corrosion. This makes CF8M more suitable for harsher environments compared to CF8.
ASTM A 351 Gr CF8 stands for cast 304 material and CF8M stands for cast SS 316

cf8m is a Sharpe Valve model # , 1000 CWP means it is rated for 1000psi Constant Working Pressure
316 stainless
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.
CF8 is a common grade of stainless steel material also known as Type 304, which is composed of 18% chromium and 8% nickel. It offers good corrosion resistance and is often used in applications where corrosion resistance is required.

It is a casting of 316 stainless, with higher values of Nickel, Chromium, and Silicon.
A351-CF8M refers to a specific grade of stainless steel defined by the ASTM A351 standard, which outlines the chemical and mechanical properties of cast stainless steels. The "CF8M" designation indicates that the alloy is austenitic, containing approximately 18% chromium and 10% nickel, with the addition of molybdenum for enhanced corrosion resistance. This grade is often used in applications requiring good strength and resistance to pitting and crevice corrosion, such as in chemical processing and marine environments.
It is a form of 316 Stainless Steel As to the designation - C (first letter) means the service it is intended to be used in this case - corrosion resistant service , F(second letter) -The second letter indicates the approximate location of the alloy on the iron-chromium-nickel (FeCrNi) ternary diagram. For users familiar with the diagram, the second letter does provide an indication of the nominal iron, nickel, and chromium content, but most people would have to obtain alloying information from a material specification. 8M - the third and fourth digits represent the maximum permitted carbon content in units of 0.01% (e.g., CF8M has a maximum of 0.08% carbon)
