What Is 347 Stainless Steel Tube?
The addition of niobium and tantalum elements plays a crucial role in stabilizing the 347 stainless steel tube alloy. Often referred to as UNS 34700 or AISI 347 tube, this stainless steel alloy is exceptionally well-suited for high temperature environments, particularly in industries where the temperature range is susceptible to chromium carbide precipitation. Consequently, the SS 347 welded tube can effectively function within a temperature range of 800°F to 1500°F. When it comes to mechanical properties, such as creep and stress cracking, grade 347 stainless steel round tubing outperforms grade 304 or 304L. Its superior characteristics make it an ideal choice for various applications.
- ASME SA213The Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes are specialized components designed for various industrial applications. These tubes are manufactured using a seamless process, ensuring excellent durability and reliability under high-temperature and high-pressure conditions.
The seamless nature of these tubes eliminates the risk of leakage, making them ideal for use in boilers, superheaters, and heat exchangers. They possess exceptional resistance to corrosion and oxidation, allowing them to withstand harsh environments.
One key feature of these alloy-steel tubes is their composition, which consists of both ferritic and austenitic alloys. This combination provides enhanced mechanical properties, including high tensile strength and excellent creep resistance. Moreover, the inclusion of austenitic alloys improves resistance to stress corrosion cracking, making these tubes highly reliable for long-term use.
These tubes are produced in compliance with strict industry specifications, ensuring their suitability for various applications and industries. They adhere to stringent quality control measures during the manufacturing process to meet the required dimensional accuracy, surface finish, and mechanical properties.
The Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes undergo thorough testing to ensure their performance meets the specified standards. This includes non-destructive testing methods such as ultrasonic examination, eddy current testing, and hydrostatic testing. These tests guarantee the integrity and quality of the tubes and provide assurance of their ability to withstand extreme conditions.
In conclusion, the Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes are essential components for industrial systems operating under high temperatures and pressures. Their seamless construction, resistance to corrosion, and mechanical strength make them reliable and efficient in various applications. Meeting industry specifications and undergoing rigorous testing ensures their exceptional quality and performance in demanding environments.
- ASME SA269This specification pertains to both seamless and welded austenitic stainless steel tubing that is intended for general service use. The material used for this tubing should possess the required chemical composition and mechanical properties to ensure reliable and durable performance. Additionally, the tubing must be able to withstand various temperatures and environments without compromising its structural integrity. This standard serves as a guide for manufacturers, suppliers, and consumers of austenitic stainless steel tubing to ensure that it meets the necessary criteria for safe and efficient use.

347 stainless steel tubing is a high-alloy steel that can resist corrosion in the air or in chemically corrosive media. Stainless steel is a kind of steel with a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as color plating to exert the inherent surface properties of stainless steel. It is used in many aspects of steel, usually called stainless steel. High-alloy steels such as 13 chrome steel and 18-8 chrome-nickel steel represent performance.
