What is Duplex & Super Duplex Steel F51 / F52 / F53 Forged Fittings ?

The excellent corrosion resistance is said to be the ASTM A182, F51, UnS S31803 Duplex Fittings which provides a wide variety of outstanding corrosion resistance, which prevents corrosion in sea water and other environmental chlorides at a temperature of filling and over 50 degrees of calcium. They have high strength in comparison with high austenitic and 22% duplex steels. They have extra ductility and are strong and work well at low temperatures.

They offer excellent resistance to environmental stress corrosion made of chloride. In both resistance and strength, they find an excellent application. Duplex Fittings for better corrosion resistance, ASTM A182 F51 UNS S31803. They are highly suited for temperatures above 300oC because they usually are precipitated by fragile micro-components.

The manufacturer performs various tests to make sure that design complies with all requirements for pressure coding and standards to qualify the design of ASTM a182 f51/f60 forged fittings. These include hydrotesting, proof testing (break-out tests), non-destructional testing (magnetic particulate testing, liquid penetrative test, pmi testing, ultrasonic testing and radiograms).

Other examinations include metallurgical testing (micro and macro tests) and other special testing such as intergranular corrosion testing and visual examination.
