Stainless Steel 317 Flanges

Stainless Steel 317 Flanges

Stainless Steel 317 and 317L are austenitic stainless steel alloys known for their exceptional resistance to corrosion and a wide range of aggressive chemicals. When it comes to constructing critical components like flanges, these alloys are the preferred choice due to their remarkable durability and performance.

Corrosion Resistance: Stainless Steel 317 and 317L are highly resistant to corrosion, even in harsh environments. This makes them ideal for flange applications where exposure to corrosive substances is a concern. These alloys contain molybdenum, which enhances their resistance to pitting, crevice, and general corrosion.

High-Temperature Performance: Flanges made from these alloys maintain their structural integrity at elevated temperatures. This makes them suitable for applications in industries such as petrochemicals, chemical processing, and heat exchangers, where high-temperature resistance is essential.

Dual Certified Alloy: The "L" in 317L signifies the low carbon content in this alloy, providing even greater corrosion resistance in specific environments. Both 317 and 317L can be used interchangeably, making them versatile options for various applications.

Ease of Fabrication: Stainless Steel 317/317L Flanges are known for their ease of fabrication, allowing for precise and complex shapes. This makes them adaptable to different flange types, including slip-on, weld neck, socket weld, and threaded flanges.

317 Stainless Steel Flanges

Versatile Application: These flanges find applications in diverse industries, including chemical processing, oil and gas, food and beverage, pharmaceuticals, and more. They are commonly used in pipe connections, where their robust and corrosion-resistant nature ensures the longevity of the system.

Compatibility: Stainless Steel 317/317L Flanges are compatible with a wide range of piping materials, further enhancing their versatility. They can be used with stainless steel, carbon steel, and other alloy piping, allowing for seamless integration into existing systems.

Low Maintenance: Due to their exceptional corrosion resistance, flanges made from 317/317L alloys require minimal maintenance, reducing downtime and operational costs.

Certifications and Standards: These flanges typically adhere to international standards like ASME B16.5 and ASTM A182, ensuring their quality and performance meet the industry's stringent requirements.
