Author: Jayesh Bhansali

Stainless Steel 304 Tubes are among the most widely used stainless steel products in the world. Known for their excellent corrosion resistance, formability, and ease of fabrication, SS 304 tubes are ideal for applications ranging from domestic architecture to high-pressure industrial processes.

In this blog, we explore the features, advantages, applications, and why SS 304 remains a top choice across diverse sectors.

What is Stainless Steel 304?

Stainless Steel 304 is the most commonly used austenitic stainless steel, composed primarily of chromium and nickel. It is part of the 18/8 family—18% chromium and 8% nickel—which provides excellent corrosion and oxidation resistance.
