Known for its superior high-temperature resistance, excellent corrosion resistance, and outstanding mechanical properties, SS 310 Round Bar has become a preferred choice across multiple industries.
In this blog, we’ll take a deep dive into the properties, applications, and benefits of 310 Stainless Steel Round Bar, helping you understand why it is widely trusted in critical industrial sectors.

What is Stainless Steel 310 Round Bar?

Stainless Steel 310 Round Bar is an austenitic stainless steel alloy that contains a higher percentage of chromium (24–26%) and nickel (19–22%) compared to standard grades. This unique composition makes it extremely resistant to oxidation, scaling, and corrosion, even at elevated temperatures up to 1100°C (2010°F) in continuous service and 1150°C (2100°F) under intermittent service.

Due to these characteristics, SS 310 Round Bar is often used in high-temperature environments, such as furnace parts, heat exchangers, power plants, and chemical industries.

Chemical Composition of SS 310 Round Bar
