Sanghvi Overseas is one of Nation's largest manufactures of 347 pipes and tubes of high quality stainless steel that are used in different industries. We sell high-quality SS 347 pipes and tubes in varying lengths and diameters that are designed in compliance with national and international raw material quality requirements.
Alloy 347 is a columbium-stabilized austenitic stainless steel which, throughout welding and sporadic heating to 800/1650°F (427/899°C), resists carbide precipitation. These pipes and tubes are also known as UNS S34700, and have strong tolerance to high temperature scales. These SS 347 Seamless Tubing, known as WNR 1.4550, are recommended for welded sections that cannot subsequently be annexed.
Our SS 347 Seamless Pipe is used at extreme temperature and, at higher temperatures, it has strong creep ability. The mechanical properties, along with the material's chemical composition, make it applicable through a large range of applications. The 347 SS Pipe is primarily used in the maritime environment, aircraft, marine architecture, machinery and laboratory furniture, as well as in the aerospace industry. The SS 347 Pipe is welded with electric resistance and is thus suitable for highly welded applications. We manufacture all sorts of pipes in various dimensions in this content grade.
Our 347 Welded Stainless Steel Tubes can be sold in sizes and shapes with customized lengths and are available at industry leading prices. It is also possible to produce and machine these SS AISI 347 pipes and tubes to satisfy our customers' piping needs.
Common austenitic stainless steels like 304, 316, and 321 include 347 stainless steel, which is frequently used in elevated temperature applications. Tantalum and columbium are added to stainless steel 347, which has excellent forming and welding properties as well as exceptional resistance to intergranular corrosion.
How Many Types of SS are There?
Stainless steel comes in three main varieties. ferritic, martensitic, and austenitic. These three different types of steel can be distinguished by their predominant crystal phase or microstructure.
