Introduction to Stainless Steel 304 Round Bars

Stainless Steel 304 Round Bars are high-quality austenitic stainless steel bars composed of approximately 18% chromium and 8% nickel, giving them excellent corrosion resistance, strength, and durability. They are designed to perform well in a wide range of environments, including high temperatures and high-pressure conditions. These bars offer a minimum tensile strength of 515 MPa and a minimum yield strength of 205 MPa, making them ideal for applications that require reliability and structural integrity. SS 304 Round Bars are available in various types, including hot-rolled, cold-drawn, and bright bars, and conform to standards like ASTM A276, ASTM A479, AMS 5639, and UNS S30400.

The versatility of SS 304 Round Bars allows them to be used in pressure vessels, industrial equipment, architectural components, and manufacturing applications. They can be supplied in customizable dimensions to meet specific project requirements. Variants such as SS 304 Rods, Black Bars, and Cold Rolled Bars (1.4301 / AISI 304) cater to different surface finishes, mechanical properties, and fabrication needs.With a combination of high corrosion resistance, excellent formability, and robust strength, SS 304 Round Bars remain one of the most widely used stainless steel materials in industries worldwide.

FAQs About Stainless Steel 304 Round Bar

It is an austenitic stainless steel grade containing about 18% chromium and 8% nickel. There are also trace amounts of carbon, manganese, silicon, phosphorus, and sulfur.

Yes. Because of its composition and melting point (around 1400 °C), it maintains performance under elevated temperatures and is used in pressure vessel applications.

The main difference is the carbon content. 304L has lower carbon, which improves weldability and reduces carbide precipitation, making it suitable for heavy welding applications.
