The material of the C&N ASME B16.5 A694 F65 flange contains various metallic elements. Among them, chromium and molybdenum effectively enhance the flange's corrosion resistance and high-temperature strength, further improving its ability to withstand harsh environments. Additionally, its extremely low phosphorus and sulfur content helps reduce embrittlement during heat treatment and welding processes, ensuring the flange maintains structural integrity and high toughness across a wide temperature range from low to high temperatures.

The A694 F65 flange material exhibits outstanding mechanical properties, featuring not only high yield strength and tensile strength but also excellent impact toughness.

A694 F65 flanges are widely used in industries such as power generation, natural gas processing, petrochemicals, offshore oil drilling, and pharmaceuticals. They are particularly suitable for oil and gas extraction and transportation systems (including sour service environments), offshore platforms, subsea pipelines, and other critical industrial connection points that require high strength, high sealing integrity, and superior corrosion resistance.
