We offer These Super Duplex Steel Forged Fittings S32750 as per DIN, ISO, JIS or ANSI Standard.
Corrosion Resistance: One of the most important advantages of Super Duplex Steel S32750 is its excellent corrosion resistance. It resists corrosion in harsh environments such as seawater, making it ideal for marine and marine applications. This resistance extends to corrosive chemicals and acids, providing a longer shelf life in corrosive environments.
Weldability: Despite its high alloy content, Super Duplex Steel S32750 is weldable by conventional welding techniques such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and shielded metal arc welding (SMAW). On.
Thermal Resistance: Super Duplex Steel S32750 has high-temperature mechanical properties and corrosion resistance, making it suitable for applications where high temperatures are commonly present. It exhibits excellent heat transfer and low-temperature expansion and increases its activity under thermal cycling conditions.
Dual microstructure: The dual microstructure of S32750 consisting of austenite and ferrite phases contributes to a better combination of mechanical properties. This microstructure provides high resistance to pitting, crack corrosion and chloride stress corrosion cracking.
High Strength: Super Duplex Steel S32750 is stronger than conventional austenitic stainless steel. This superior strength enables using flat frames in construction, reducing weight and cost while preserving structural integrity. It also provides excellent resistance to stress corrosion, cracking, and fatigue.
Super Duplex Steel Forged Fittings S32750 applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Oil & Gas Industry: Super-duplex steel meshed fittings are widely used in offshore and onshore oil and gas exploration and production due to their high strength, corrosion resistance, chloride stress corrosion and crack resistance. They are used in pipelines, subsea equipment, valves, and other critical components.
Pulp and Paper Industry: Super-duplex steel mesh fittings are used in the pulp and paper industry, where highly corrosive chemicals and acidic environments are used in digesters, bleaching plants and piping systems.
Desalination plants: Super duplex steel’s corrosion resistance makes it suitable for use in desalination plants that treat seawater as potable water. These materials are used in pumps, piping systems and heat exchangers.
Chemical applications: Chemical industries where environmental corrosion is prevalent prefer super duplex steel mesh fittings due to their resistance to various chemical corrosion, acids, and solvents. They are used in reagents, heat exchangers, and other applications.
Understand application requirements: Identify the specific conditions in which the fitting will be used. Consider factors such as temperature, pressure, corrosion resistance, and the type of liquid or gas flowing into the system.
Size and thickness: Choose fittings that match the thickness and thickness required for your piping system. Consider nominal pipe size (NPS), pressure rating, and connection type (e.g., threaded, socket-welded, or butt-welded).
Certifications and standards: Ensure fittings meet industry standards and appropriate certifications. For example, ASTM A182/A182M is the standard specification for forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves.
Material Properties: Super duplex stainless steel like S32750 offers excellent corrosion resistance, strength, and weldability. Make sure these properties match your application’s requirements.
