Stainless steel is one of the main materials commonly used in valves, among which the most commonly used are CF3, CF8, CF3M, CF8M.

 

So, what's the difference between these materials? What do they stand for? Let's take a look.

 

1. The first character (C) means the alloy is intended for "Corrosion Resistant" service.

2. The second character (F) is the approximate location on the iron-chromium-nickel (FeCrNi) ternary diagram and indicates the iron, chromium and nickel content.

3. The third character (3 or 8) represents the maximum carbon content in increments of 0.01%. Therefore, 3 represents 0.03%, and 8 represents 0.08%.

4. Finally, the character (M) states that Molybdenum is present.

 

Stainless steel is resistant to weak corrosive media such as air, steam, water, etc. It is widely used in valves.
