Stainless Steel 347 and 347H are austenitic stainless steel alloys with enhanced properties compared to traditional 304 and 316 stainless steel alloys. One of the most common uses for these alloys is the manufacturing of flanges. Flanges are the most critical component of piping systems for their ability to connect pipes, valves, and other components essential to any manufacturing facility, petrochemical plant, or refinery.

Various Stainless Steel 347 flanges include Weld Neck, Slip-On, Threaded, Blind, Lap Joint, Socket Weld, and Orifice. Each flange type has a specific purpose, depending on its application in the industry. Weld Neck Flanges are the most commonly used type because of their durability, reliability, and ability to withstand high temperatures and high-pressure situations. Socket Weld Flanges are used for small-diameter piping systems, while Blind Flanges are used to close the end of a piping system. Slip-On Flanges are best for low-pressure applications, and Orifice Flanges are used in systems that require precise flow rate measurement.

Stainless Steel 347 Flanges are commonly used to manufacture piping systems and valves connecting different system components. The 347H variant is used where high-temperature resistance is required. The flanges also find use in the maintenance and repair of various industries, and the growing applications of SS 347 Flanges and 347H are expected to significantly increase demand.

One of the most significant advantages of using Stainless Steel 347 and 347H Flanges is their corrosion-resistant properties. The alloy’s chromium and nickel content makes it highly resistant to rust and tarnishing, making it an ideal choice for harsh environments. They also offer outstanding welding characteristics, saving time and cost in welding operations. Moreover, the enhanced mechanical properties of SS 347H Flanges, including high tensile strength and toughness, make them a more reliable option than other types of stainless steel.

Stainless Steel 347 and 347H Flanges are excellent for piping systems in various industries due to their durable and reliable properties. They offer several advantages, including superior resistance to corrosion, good welding characteristics, and enhanced mechanical properties.
