Our extensive inventory of SS 304 Pipes & Tubes includes a full range of seamless, welded, and ERW products certified to international standards like ASTM and ASME, ensuring superior performance for any industrial application.
What is Stainless Steel 304?
Stainless Steel 304 is the most common austenitic stainless steel, often referred to as "18/8" due to its composition of approximately 18% chromium and 8% nickel. This chemistry is the key to its performance, providing a robust, passive layer that protects the steel from a wide range of corrosive environments. It is renowned for its excellent formability, weldability, and hygienic properties, making the 304 ss pipe a staple in countless industries.
Types of Stainless Steel 304 Pipes & Tubes
We are a leading manufacturer of both Stainless Steel 304 Seamless Pipes & Tubes and Stainless Steel 304 Welded Pipes & Tubes.
- SS 304 Seamless Pipes & Tubes: Produced from a solid billet, these offer maximum strength and pressure resistance. 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. These seamless pipes and tubes are used in many different fields, such as power, engineering, construction, and many more.
- SS 304 Welded Pipes & Tubes: The Stainless Steel 304 Welded Pipe is made by welding a thin strip or sheet together. These Pipes have a high mechanical strength because of their duplex microstructure and nitrogen alloying. 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. 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.
There are different standards, sizes, shapes, dimensions, and grades for these Stainless Steel 304 Pipes and Tubes available at Amardeep Steel Centre such as round, square, rectangular, and hydraulic types of seamless, welded, and LSAW pipes.

FAQ’s About Stainless Steel 304 Pipes & Tubes
Is 304 stainless steel good quality?
Yes, 304 stainless steel is generally considered a good quality stainless steel. It's actually the most commonly used stainless steel grade worldwide, prized for its balanced properties. It offers a good level of corrosion resistance, is easy to form and weld, has decent strength, and is relatively easy to maintain. While other grades like 316 offer even better corrosion resistance (especially against chlorides and acids), 304 is a versatile and cost-effective choice for many applications.
What is the difference between Stainless Steel 304 & 316 pipes?
316 contains many similar chemical and mechanical properties as 304 stainless steel. To the naked eye, the two metals look the same. However, the chemical composition of 316, which is made up of 16% chromium, 10% nickel, and 2% molybdenum, is the main difference between 304 and 316 stainless steel.
What percentage is 304 stainless steel?
With a typical composition of around 18% chromium and 8% nickel, 304 stainless steel is often referred to as "18/8" stainless.
Where can I buy 304 stainless steel pipes and tubes?
As Amardeep Steel Centre, a leading manufacturer and supplier of stainless steel products, we offer a wide range of 304 stainless steel pipes and tubes. You can purchase them directly from us. We cater to various needs, from standard sizes to custom requirements.
