Countless steel alloys are available on the market, each with unique properties and characteristics. For those seeking high corrosion resistance and durability, the 347-round bar is worth considering. This alloy is known for withstanding elevated temperatures and corrosive environments. In this article, we’ll explore the properties and applications of 347 round bars to give you a better understanding of their capabilities.
What is 347 Round Bar?
347 Round Bar is an austenitic stainless steel alloy with excellent corrosion and oxidation resistance. Its excellent high-temperature strength makes it the ideal choice for extreme heat applications such as furnace and exhaust components. The 17 percent chromium content of 347 gives it superior resistance to corrosion and precipitation of other metals, while its niobium addition helps protect against intergranular attack at temperatures up to 1500°F (816°C). This material also offers good mechanical properties, weldability, formability, and machinability. Additionally, 347 Round Bar can be used in various industrial applications, including chemical processing equipment, power generation components & more.
Benefits of 347 Round Bar
347 stainless steel round bar offers numerous benefits in various applications. Firstly, it is highly resistant to oxidation and corrosion due to its high chromium content. It is also non-magnetic and has excellent forming characteristics, making it an ideal choice for welding or brazing applications. Additionally, this alloy has a good creep strength at elevated temperatures; thus, it performs well even under demanding conditions like elevated temperatures or extreme pressure. Lastly, its ease of fabrication further adds to its appeal as a construction material for industrial settings such as chemical processing plants or nuclear power plants.
Properties of 347 Round Bar
Chemical Composition
The 347 round bar is a stabilized austenitic stainless steel alloy with a higher chromium and nickel content than its 321 counterparts. It also has the addition of tantalum, which stabilizes the alloy significantly. Tantalum also enhances its resistance to corrosion, making it an ideal material for high-temperature environments.
Heat Treatment
The heat treatment of 347 round bars involves annealing and hardening processes. Its high-temperature resistance characteristics make it a popular choice for continuous heat treatment.
Corrosion Resistance
One of the primary advantages of 347 round bars is their superior corrosion resistance, especially in environments with high levels of chlorides. These bars have excellent resistance to corrosion cracking, pitting, and crevice corrosion, making them suitable for use in chemical processing plants, oil and gas wells, and other highly corrosive environments.
Applications
The 347 round bar is a popular choice for many industrial applications thanks to its superior strength, durability, and corrosion resistance. Its main applications include:
• Chemical Processing: 347 round bars are commonly used in chemical processing applications, where they are exposed to highly corrosive environments and high temperatures.
• Aerospace: The aviation industry relies on the 347-round bar to manufacture exhaust systems, engine parts, and hydraulic lines. Its high-temperature resistance is a particular advantage in this area.
• Oil and Gas: The oil and gas industry is another sector that relies heavily on 347 round bars. They are used in pumps, valves, and other equipment that withstand harsh and corrosive conditions.
• Food and Beverage Processing: Due to their superior corrosion resistance, 347 round bars are used to manufacture food and beverage processing equipment.
Conclusion:
347 round bars are among the most robust and versatile stainless steel alloys. They are renowned for their high-temperature resistance, corrosion resistance, and durability, making them ideal for various industrial applications. If you’re considering 347 round bars for your next project, you can rest assured that you’re investing wisely in a reliable and proven alloy.
