Stainless Steel 304 Pipes & Tubes

Grade 304 Stainless Steel Pipes are the most flexible and commonly used stainless steel grade on the market. Stainless Steel 304 grade is the most commonly used alloy in the industry. Stainless Steel 304 Welded Pipes have a high mechanical strength because of their duplex microstructure and nitrogen alloying. Some people refer to Stainless Steel 304 Seamless Pipes as austenitic-ferritic stainless steels because they are made up of about 50 percent austenitic and 50 percent ferritic stages. The nominal bore size of Stainless Steel 304 Seamless Pipe ranges from 1/2 inch to 16 inches, the nominal bore size of ERW pipes ranges from 1/2 inch to 24 inches, and the nominal bore size of EFW pipes ranges from 6 inches to 100 inches. All pipes range in size from 1/8 inch to 30 inches. The Stainless Steel 304 Welded Pipe is made by welding a thin strip or sheet together. There are different standards, sizes, shapes, dimensions, and grades for these Stainless Steel 304 Pipes/Tubes avaialble at Amardeep Steel Centre such as round, square, rectangular, and hydraulic types of seamless, welded, and LSAW pipes. Amardeep Steel Centre is a well-known and well-established company that makes, stocks, and sells high-quality ASTM A312 TP Stainless Steel 304 Pipes and Tubes. A heat exchanger is a common place where Stainless steel 304 pipe is used. A heat exchanger is a system that moves heat from one fluid to another. Since SS 304 welded pipe is more cost-effective, it is more often used in heat exchangers. Heat exchangers need to be moderately resistant to corrosion and have good tensile strength. These Stainless Steel 304 Seamless Tubes/Pipes are used in many different fields, such as power, engineering, construction, and many more. We also offer our clients a competitive range of SS 304 pipes and tubes.
