Our Class 150 Forged Steel Raised Face Weld-Neck Flanges are manufactured from ASTM A105 mild steel. Dimensions and tolerances meet ANSI/ASME B16.5 specifications and are painted black for corrosion resistance. We manufacture these flanges in domestic (AIS) and import options, and our machine shop can modify ANSI/ASME flanges to spec.
