ANSI / ASME B16.5 Forged Flange ASTM A182 Grade LF2 Alloy Steel Weld Neck Flange
The ASTM A350 LF2 flange is designed to maintain toughness and impact resistance which is suitable for low-temperature applications down to -50°F (-45°C) and also for higher temperatures. They are commonly used in oil and gas pipelines, chemical processing, and other industries where durability and resistance to low temperatures are essential.
