We offer Stainless Steel 347 Forged Fittings as per DIN, ISO, JIS or ANSI Standard.
Due to their exceptional properties, Stainless Steel 347 Forged Fittings are essential components across many industrial sectors. Renowned for their corrosion resistance, they find widespread application in marine environments, enduring the rigours of saltwater exposure with longevity and reliability. In the construction industry, stainless steel fasteners play a pivotal role in structural assemblies, providing secure connections while maintaining structural integrity in outdoor and exposed settings.
Material: Ensure that the fittings are made of 347 stainless steel, which provides corrosion resistance, high temperature and excellent mechanical properties. Check with the manufacturer or supplier.
Pressure and Temperature Analysis: Consider your system’s maximum operating pressures and temperatures and choose fittings that can withstand these conditions. Check the fittings’ pressure and temperature to see if they meet or exceed your requirements.
Size and connection type: Choose fittings that match your piping system’s size and connection type. The most common connection types for mesh fittings are threaded (NPT, BSP) and socket welds.
Configuration: Based on your piping design and installation needs, select the appropriate installation system (e.g., elbow, tee, coupling, union). Ensure the fitting provides the necessary flow direction and connectivity for your application.
Stainless Steel 347 Forged Fittings exhibit weak magnetic properties due to their austenitic microstructure. While they may attract a magnet slightly, their magnetism is typically much lower compared to ferritic or martensitic stainless steels, making them essentially non-magnetic in practical applications.
Yes, Stainless Steel 347 Forged Fittings can be recycled after use. Stainless steel is highly recyclable, and the 347 alloy retains its properties through multiple recycling processes without significant degradation. Recycling stainless steel reduces environmental impact, conserves resources, and supports sustainable manufacturing practices.
Yes, Stainless Steel 347 Forged Fittings are suitable for cryogenic applications. They maintain their mechanical properties, corrosion resistance, and toughness at low temperatures, making them ideal for use in cryogenic storage tanks, liquefied gas systems, and other applications requiring reliable performance in extremely cold environments.
Yes, Stainless Steel 347 Forged Fittings can be used for underground applications. Their corrosion resistance, including resistance to chloride-induced stress corrosion cracking, makes them suitable for underground piping systems in various industries such as oil and gas, water treatment, and utilities, where they can withstand harsh underground environments.
