What is the difference between F51, F53, and F60 duplex steel?
F51, F60, and F53 are ASTM A182 forged duplex stainless steels used for high-strength, corrosion-resistant components. F51 (22Cr, UNS S31803) is the standard 22% Cr grade, while F60 (22Cr, UNS S32205) is a tighter-composition version of F51 with better corrosion resistance. F53 (25Cr, UNS S32750) is a super duplex, offering superior pitting resistance and strength.

FAQ
Q: Can ASTM A182 F51/F53/F60 tubesheets be used in seawater applications?
Yes, all three grades are highly resistant to pitting and crevice corrosion in seawater, with F53 and F60 preferred for long-term offshore use.
Q: What is the maximum service temperature for these tubesheets?
F51: up to 300°C
F53 / F60: up to 350°C in continuous operation
Q: Are these tubesheets compatible with standard 316 / 316L stainless steel tubes?
Yes, but mechanical and galvanic considerations should be checked in design. Duplex steels have higher strength.
Q: What certifications are available from GNEE?
Mill Test Certificates (EN 10204 3.1 / 3.2)
ISO9001, SGS, BV inspection reports
PED / ASME compliance on request
