B16.5 Forged Flange ASTM A182 F44 S31254 SMO254 Welding Neck RF FF
ASTM A182 F44 Flange is described as a 6% Mo Flanges. The steel combines moderate mechanical strength (typically over 300 MPa yield strength) and high ductility with excellent corrosion resistance in seawater and a variety of industrial environments. Typically the alloy has a PREn(Pitting Resistance Equivalent) of 42-44 which ensures that the resistance to pitting corrosion is high.

ANSI Flanges or ASME Flanges?
Some customers call us asking for ANSI Flanges and others call us asking for ASME Flanges. We even have customers calling us to ask if there is a difference between ANSI and ASME Flanges. In reality there is no difference. ASME is 'The American Society Of Mechanical Engineers' and ANSI is the 'American National Standards Institute'. The ANSI standards (i.e. ANSI B16.5 or ANSI B16.47) are developed by ASME working under procedures accredited by ANSI and hence these standards are adopted by ANSI to become the standards for ANSI Flanges.
