An Overview of SS 347 Forged Fittings

When choosing the right fittings for your industrial piping systems, SS 347 forged fittings are a popular option for various reasons. SS 347 offers excellent strength, corrosion resistance, and durability under high temperatures as a type of austenitic stainless steel. In this comprehensive overview, we’ll take a closer look at what SS 347 forged fitting is, their unique properties, and why you should consider using them for your next project.

What is SS 347 forged fittings?

SS 347 forged fittings are high-caliber stainless steel components used in piping systems to combine two or more pipe pieces. They’re often used in pressure applications due to their exceptional durability and corrosion resistance properties. These fittings offer superior strength over welded joints and improved manufacturing efficiency and cost savings. They are available in various shapes, sizes, and wall thicknesses for various applications.

Unique properties of SS 347 forged fittings

SS 347 forged fittings have several unique properties, making them a popular choice in high-temperature and high-pressure piping systems. Some of these properties include:

  • High resistance to corrosion and oxidation at temperatures up to 800°C
  • Good creep strength and stress-rupture resistance
  • High strength and toughness
  • Excellent weldability and formability

Types of Stainless steel 347 forged fittings

Socket weld fittings:

The most widely used type of Stainless steel 347 forged fittings is socket weld fittings. Moreover, they offer a variety of benefits, including exceptional corrosion resistance, high strength, and low maintenance requirements. Furthermore, many different types of applications involving pressure piping systems find socket welds well-suited for use. Consequently, these fittings provide a reliable and efficient solution for industries that demand durable and long-lasting connections in their critical piping networks.

Threaded fittings:

In plumbing applications, threaded SS 347 forged fittings primarily serve to securely connect pipes and other components together without the need for welding or soldering. Furthermore, threaded SS 347 forged fitting connections outperform traditional pipe couplings in terms of leak tightness.

Buttweld elbow:

These products allow easy connection between tubes or pipes, creating strong joints capable of withstanding high pressures and temperatures. With an incredibly robust structure and superior metallurgical composition, they offer remarkable reliability even in corrosive and thermal shock environments, making them ideal for various industrial applications, from energy production to food processing and pharmaceuticals, ensuring seamless hygienic functionality without the risk of failure or contamination.


These are heavy-duty SS347 forged flanges featuring raised face (RF) design connections commonly found in larger diameter pipe installation projects where simple buttweld elbow joints would not suffice due to their overall size limitations with respect to bending radius regulations & leakage potential concerns. These flanged connections often form capsule-like sealed closure points within networks containing varying levels of internal/external pressures, thus providing additional dependable security throughout the whole system using simple yet effective bolt/nut tightening configurations allowing them to handle extreme fluctuations while sustaining total integrity whether you’re dealing with lightweight beverage carry vessels between breweries up through ultra-durable shipbuilding materials connecting large scale oil tankers/cargo ships across seas alike.

Applications of SS 347 forged fittings

Various industries and applications commonly use these products, including petrochemicals, oil and gas, chemical processing, power generation, and aerospace. They are ideal for use in piping systems that require high strength and resistance to corrosion and oxidation at high temperatures. Some specific applications of SS 347 forged fittings include:

  • High-pressure piping systems
  • Heat exchangers
  • Chemical reactors
  • Boiler tubes
  • Aircraft exhaust systems


In conclusion, SS 347 forged fittings are an excellent choice for industrial piping systems requiring strength, durability, and resistance to high temperatures and corrosion. With their unique properties and wide range of applications, Stainless steel 347 forged fittings are a reliable and cost-effective solution for your piping system needs. If you’re considering using these products for your next project, consult a trusted supplier or manufacturer to ensure you’re getting high-quality fittings that meet your specific requirements.
