Valour Alloys Inc., we carry a full inventory and Supply Stainless Steel 347H Flanges products in a variety of sizes widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability.
Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 – 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F (537°C). In most instances, the carbon content of the plate enables dual certification.
Flanges are critical components in piping systems, used to connect pipes, valves, and other equipment. They provide a secure and leak-proof connection, allowing for easy assembly and disassembly. Flanges come in various materials to suit specific requirements, and 347H flanges are a type designed for high-temperature and high-corrosion environments.
347H flanges are typically made from stainless steel alloy 347H, which is a high-temperature version of stainless steel 347. The "H" in 347H stands for "high carbon," indicating that this alloy contains higher carbon content compared to standard 347 stainless steel. This high carbon content provides improved high-temperature strength and resistance to sensitization, making it suitable for applications in elevated temperature and corrosive environments.

Stainless Steel 347H Flanges Manufacturer

Stainless Steel 347H Flanges Exporter
ISO 9001:2015, PED/27/EC and OHSAS 18001:2015 Approved Manufacturer of Stainless Steel 347H Flanges in Specification ASTM A182 347H and Types Like 347H Weldneck Flange, 347H Blind Flange, 347H Socketweld Flange, 347H Slip On Flange, 347H Threaded Flange, 347H Laped Joint Flange, 347H Screw Flange, 347H Plate Flange, 347H WNRF Flange, BLRF Flange, SWRF Flange, 347H SORF Flange etc.
Material Composition: 347H flanges are primarily composed of stainless steel alloy 347H, which includes elements like chromium, nickel, and molybdenum, in addition to the higher carbon content. These elements contribute to the flange's resistance to high-temperature oxidation and corrosion.
High-Temperature Applications: 347H flanges are specifically designed for applications where temperatures can reach or exceed 800°C (1472°F). They are commonly used in industries such as petrochemical, chemical processing, and power generation.
Corrosion Resistance: The 347H alloy provides excellent resistance to a wide range of corrosive environments, including those containing sulfuric acid, hydrochloric acid, and other aggressive chemicals.
Sensitization Resistance: One of the key advantages of 347H stainless steel is its resistance to sensitization, a condition that can occur in stainless steel at elevated temperatures, leading to intergranular corrosion. This property ensures the long-term integrity of flanges in high-temperature applications.
Weldability: 347H stainless steel is easily weldable and is often used in applications where welding is required. This makes it a practical choice for fabricating flanges and other components.
Variety of Flange Types: 347H flanges come in various types, including weld neck, slip-on, socket weld, and threaded flanges, among others, to accommodate different piping system requirements.
347H flanges are a specialized type of stainless steel flanges designed for high-temperature and high-corrosion environments. Their unique composition and properties make them suitable for a wide range of industrial applications where reliability and performance under extreme conditions are crucial.
