Frequently Asked Questions
Q. What does CF8M stand for?
A. As with CF3M, the first character (C) means the alloy is intended for "Corrosion Resistant" service. The second character (F) is the approximate location on the iron-chromium-nickel (FeCrNi) ternary diagram and indicates the iron, chromium and nickel content. The third character (8) represents the maximum carbon content in increments of 0.01%. In this instance, 0.08%. Finally, the character (M) states that Molybdenum is present.
