ASTM B546 UNS NO8825 Steel Forged Flanges ASTM B564 Incoloy 825 UNS NO8825

The ASTM B564 specification plays a pivotal role in the manufacturing and application of forged flanges, covering materials that include high nickel alloys. Among these, the UNS N10276, UNS N08825 (widely known as Alloy 825 B564), and UNS N06625 are paramount for industries requiring high corrosion resistance and durability under severe conditions. These material grades ensure that flanges can withstand extreme environments without compromise.

Moreover, the ASTM A105 flange is renowned for its carbon steel forging, making it suitable for ambient- and higher-temperature service in pressure systems. On another front, the ASTM A182 F348 flange represents a chromium-nickel stainless steel alloy forged fitting, engineered for performance in high-temperature scenarios.

Each of these standards—ASTM B564 and ASTM A105/A182—serves distinct purposes but collectively underscores the importance of selecting the proper flanged connections to ensure integrity and reliability of piping systems across various industries. The choice between these materials depends on specific service conditions including temperature ranges and chemical exposure which they are expected to endure.
