We supply these Super Duplex Steel Forgings in accordance with DIN, ISO, JIS or ANSI Standard.
Corrosion Resistance: Super duplex stainless steel forgings deliver outstanding resistance to corrosion, particularly in aggressive settings involving chlorides, acids and seawater. This capability surpasses that of conventional duplex austenitic stainless steels.
Weldability: Super duplex steel forgings can typically be welded when suitable welding methods and filler materials are used. This eases both design and fabrication, cutting down on production and production time.
Fatigue resistance: Thanks to their excellent fatigue resistance, super duplex steel forgings can endure cyclic loading conditions without breaking down. This characteristic proves valuable for pressure vessels, pipelines and structural components exposed to fluctuating loads.
Hardness: Super duplex steel forgings stay hard even at low temperatures, which makes them well suited to cryogenic applications. These properties matter in industries like LNG (liquefied natural gas), transportation, and storage.
Strength: Super duplex steel forgings offer greater strength than conventional austenite and duplex stainless steel. This renders them appropriate for industries demanding high levels of mechanical energy, such as those in the offshore and marine environment, chemical manufacturing and oil and gas industries.
Super Duplex Steel Forgings have uses as varied as the industries that rely on them, led chiefly by the aerospace, railway, construction and automotive sectors along with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Oil and Gas Industry: Super-duplex steel mesh finds broad application across the oil and gas sector in components like valves, pumps, pipelines, offshore platforms and more. Its corrosion resistance, high strength and good weldability under harsh conditions make it ideal for these uses.
Pulp and Paper Industry: Within the pulp and paper industry, it serves in digesters, bleachers, washers, pipelines and other equipment thanks to its resistance to chemical corrosion and high-temperature
Marine Applications: For marine uses, super-duplex steel wings are employed in areas such as propeller shafts, submarine pipelines and offshore platforms owing to their corrosion resistance and strong mechanical properties
Desalination plants: Super duplex steel grids are the choice in desalination plants across various uses including pumps, piping and heat exchangers because of their resistance to chloride-induced stress corrosion cracking
Chemical applications: It also appears in chemical applications like reactors, heat exchangers and storage tanks where resistance to corrosion from acids, alkalis and other harmful chemicals is needed
Water resistance: Super Duplex steel is recognized for its outstanding resistance to corrosion, particularly in demanding settings like marine and chemical uses Assess the degree of corrosion resistance your application demands and pick the Super Duplex grade to match. Common examples include UNS S32750 (also referred to as SAF 2507) and UNS S32760.
Cost: Taking into account the upfront material cost along with any extra expenses tied to manufacturing, welding, and maintenance, weigh the prices of various super-duplex steels to identify the best value. Kari satisfies the cost and performance requirements of your application.
Weldability: Verify the weldability of the super duplex steel grade, particularly if the forgings are to be welded during fabrication or installation. Certain grades might need preheat treatment or post-welding steps to preserve corrosion resistance and mechanical characteristics.
Temperature and Pressure: Factor in the operating temperature and pressure conditions that the forgings will face. Make sure the chosen super duplex steel grade can endure these conditions without sacrificing its integrity.
Mechanical properties: Identify the mechanical properties required for your application, such as tensile strength, yield strength, and impact resistance. Various types of super duplex steel may offer differing mechanical properties, so select the grade that suits your functional needs.
