Stainless 317L Buttweld flanges are made of a low-carbon alloy that has increased amounts of nickel, chromium, and molybdenum. Alloy 317L exhibits superior resistance to general and chloride corrosion. It is also resistant to attack by sulfuric acid at temperatures of up to 120degF. 


The alloy exhibits limited iodide and chloride corrosion resistance but tends to pit when exposed to phosphates, bromides, or chloride solutions.


Stainless 317L Buttweld flanges are available in a variety of sizes, materials, and types. These high-quality flanges are used to attach the pipe to vessels. Their stainless steel construction ensures safety and durability. 


The flange's low-profile design helps make it easier to install and maintain. These flanges are commonly used in marine applications, oil and gas pipelines, as well as in oil and gas pipelines.


Stainless 317L Buttweld flanges are manufactured to a precise specification using the best raw materials and advanced technology. The range of sizes and types of these flanges is impressive and you can be assured of the quality and dependability of your piping system. 


Stainless 347 Buttweld flanges are an excellent choice for many applications. And don't forget, if you're looking for an excellent flange, look no further.


Stainless 317L Buttweld flanges come with a variety of other features. These fittings are also known as End Caps, Stub Ends, or Vanstone Flared Laps. They feature a rotating backup flange that seats against the back surface of the Stub End. If you're looking for a high-quality buttweld flange, Dynamic Forge and Fittings (I) Pvt. Ltd. produces them.


A major advantage of Stainless 317L Buttweld flanges is their increased resistance to chemical attack. Their sturdiness is unparalleled and allows you to handle the toughest of applications. As a result, they are a superior choice for critical and high-temperature piping applications. These flanges are based on ASME B16.9 buttweld pipe fittings.



As austenitic stainless steel, alloy 317L is stronger and more resistant to corrosion than the conventional alloy 316. However, because of its low carbon content, alloy 317L requires low-speed machining and constant feeds to minimize the tendency to figure harden. Unlike grade 304 stainless steel, alloy 317L can be welded using most traditional resistance and fusion methods.
