Duplex Steel S31803 F51 Flanges

Duplex Steel S31803 F51 Flanges

Citizen Metals is a distinguished manufacturer of a wide range of Duplex UNS S31803 A182 F51 Flanges, which is the most widely used duplex (ferritic/austenitic) stainless steel. Duplex Steel UNS S31803 Slip On Flanges are extremely corrosion resistant and work hardenable alloys. ASTM A182 Duplex S31803 Blind Flanges contains larger amounts of chromium in comparison with other steels and thus has good corrosion resistance. Duplex Steel F51 Spectacle Blind Flanges has high resistance to various types of corrosion. Duplex Steel UNS S31803 Socket Weld Flanges has high general corrosion resistance. ASME SA 182 Duplex S31803 Weld Neck Flanges combines good mechanical strength and ductility with moderate to good corrosion resistance in a variety of environments.

Duplex Steel S32205 F60 Flanges

Duplex Steel S32205 F60 Flanges

Citizen Metals is a distinguished manufacturer and exporter of a wide range of Duplex Steel UNS S32205 A182 F60 Flanges, which has high general corrosion resistance. Duplex Steel UNS S32205 Slip On Flanges finds applications due to both excellent corrosion resistance and high strength. ASTM A182 Duplex S32205 Blind Flanges are much more resistant to stress corrosion cracking than standard austenitic steels. At temperatures above 300 Degree C, the brittle micro-constituents of Duplex Steel F60 Spectacle Blind Flanges undergo precipitation. Duplex Steel UNS S32205 Socket Weld Flanges is characterized by high yield strength, and two times that of the standard austenitic stainless steel grades. The designation of ASME SA 182 Duplex S32205 Weld Neck Flanges reflects the amounts of chromium (22 %) and nickel (5 %) in the alloy.

Super Duplex Steel S32750 F53 Flanges

Super Duplex Steel S32750 F53 Flanges

Citizen Metals is a distinguished distributor and exporter of a wide range of Super Duplex UNS S32750 Flanges, which has improved strength over ferrite and austenitic steel grades. Super Duplex Steel UNS S32750 Grade F53 Slip On Flanges is designed to feature high strength, stress corrosion cracking, resistance to pitting, erosion corrosion and corrosion fatigue, strong weldability, and crevice corrosion. Super Duplex UNS S32750 Blind Flanges is often used in injection and ballast water systems, offshore platforms, process and service water systems, heat exchangers, fire-fighting systems, etc. Alloy UNS S32750 Spectacle Blind Flanges is designed for applications which demand exceptional strength and corrosion resistance. High molybdenum, chromium and nitrogen content in Super Duplex S32750 Weld Neck Flanges help the material withstand pitting and crevice corrosion.

Super Duplex Steel S32760 F55 Flanges

Super Duplex Steel S32760 F55 Flanges

Citizen Metals is a distinguished distributor, trader, and exporter of a wide range of Super Duplex UNS S32760 F55 Flanges, which is supplied in the hot worked and solution annealed condition. Super Duplex S32760 Slip On Flanges cannot be hardened by heat treatment but stronger surface strengths can be achieved by cold working. High impact strength at sub-zero temperatures, these Alloy UNS S32760 Blind Flanges displays excellent corrosion resistance. Super Duplex 2507 Spectacle Blind Flanges is often used in fire-fighting systems, Oil and gas industry equipment, heat exchangers, Offshore platforms, process and service water systems, etc. These Alloy 2507 Weld Neck Flanges is a highly alloyed stainless steel designed for use in aggressive environments.
