When it comes to stainless steel products, SS 304 Pipe is one of the most commonly used materials across the globe. From household applications to critical industrial sectors, it has proven its reliability and versatility. Known for its balance of strength, corrosion resistance, and affordability, stainless steel 304 pipes are a practical choice for a wide range of uses.
In this article, we’ll cover everything you need to know about Stainless Steel 304 Pipes from their properties and benefits to applications, types, and buying tips.
Understanding SS 304 Pipe
SS 304 Pipe is made from stainless steel grade 304, which is part of the austenitic stainless steel family. This grade contains 18% chromium and 8% nickel, which is why it’s often referred to as 18/8 stainless steel.
304 stainless steel offers an excellent combination of durability, formability, and resistance to corrosion. These qualities make SS 304 pipes the backbone of industries like construction, oil and gas, food processing, and pharmaceuticals.
Why Choose SS 304 Pipe?
Here are the main reasons why industries prefer SS 304 pipes:
- Corrosion Resistance – Works effectively in both mild and harsh environments.
- Strength and Durability – Withstands high pressure and temperature.
- Ease of Fabrication – Can be easily cut, welded, and formed.
- Hygienic Properties – Does not react with food or beverages, making it ideal for sanitary applications.
- Affordability – Provides great value compared to other stainless steel grades.
Chemical Composition of SS 304 Pipe
The chemical balance of stainless steel 304 ensures its high performance:
- Chromium (Cr): 18–20%
- Nickel (Ni): 8–10.5%
- Carbon (C): ≤ 0.08%
- Manganese (Mn): ≤ 2%
- Silicon (Si): ≤ 1%
- Phosphorus (P): ≤ 0.045%
- Sulfur (S): ≤ 0.030%
- Iron (Fe): Balance
This mix allows SS 304 Pipe to resist rust and chemical damage while maintaining strength.
Mechanical Properties of SS 304 Pipe
- Tensile Strength: ≥ 515 MPa
- Yield Strength: ≥ 205 MPa
- Elongation: 40% (min)
- Hardness: ≤ 201 HB
- Melting Point: 1400–1450 °C
Thanks to these properties, SS 304 Pipe performs well in high-pressure and high-temperature applications.
