FAQ

What is the difference between ASTM A182 F304 and ASTM A182 F316 flanges?

The main difference is in their composition. ASTM A182 F316 contains molybdenum (2-3%) in addition to the chromium and nickel found in F304, which provides better corrosion resistance, particularly against chlorides and marine environments. As a result, ASTM A182 F316 flanges are more suitable for highly corrosive applications.

How should ASTM A182 F304 flanges be maintained?

Regular inspection for signs of corrosion, leaks, or mechanical damage is important. Proper cleaning and maintenance of the flange surfaces, as well as ensuring that gaskets and bolts are in good condition, will help maintain their performance.
