ASTM B564 UNS N10665 Flange

ASTM B564 UNS N10665 Flange is a type of flange that is made from the material Hastelloy B2. Hastelloy B2 is a nickel-molybdenum alloy with a low carbon content. This alloy is known for its excellent resistance to hydrochloric acid, sulfuric acid, and other highly oxidizing and reducing solutions. Hastelloy B2 also has excellent stress corrosion cracking resistance, which makes it ideal for use in environments that are prone to corrosion.

The flange standard for ASTM B564 UNS N10665 Flange is ANSI B16.5. This standard is used to define the dimensions, pressure ratings, and materials for flanges used in piping systems. 
Standard: ASME B16.5, B16.47, DIN, EN, JIS, BS
Types: SW, WN, LWN, SO, Threaded, Blind, Spectical blind, lap jiont, ring, disc
Size: 1/2"-60"
Class: 150#, 300#, 400#, 600#, 900#, 1500#, 2500#
