ansi b16.5 2 inch pipe carbon steel flange class125 A694 flange
ASTM A694 flanges are available in different grades such as F42, F52, F60, F65 and F70.
The difference is in the chemical composition. ASME SA694 High Yield CS F52 Sliding Flanges contain Carbon, Silicon, Manganese, Phosphorus, Sulfur, Molybdenum, Nickel, Chromium, Copper, Vanadium and Niobium in their composition. Low temperature carbon steel in A694 specification for service in low temperature applications. Our high production CS A694 pipe flanges have a yield strength of 36ksi and are normalized for good grain structure. High-production CS A694 Orifice Plate Flanges provide maximum machinability when normalized, annealed or forged, with average strength and a low-cost leak-proof connection.
