Corrosion & Fatigue Resistance ASME B16.5 Alloy Steel Flanges Class 400

Corrosion & Fatigue Resistance ASME B16.5 Alloy Steel Flanges Class 400

1. Product Description

Our high-strength Alloy Steel Flanges are manufactured from premium chromium-molybdenum steel (e.g., F11, F22, F91) as specified in standards such as ASTM A182. They are produced through precision forging, heat treatment, and machining. Designed specifically for demanding working conditions, these flanges offer exceptional mechanical properties and durability, serving as critical connecting components in high-temperature, high-pressure, and corrosive medium pipeline systems.
