Stainless Steel 310S Round Bars are one of the most widely used products in the engineering and industrial sectors, recognized for their exceptional heat resistance, durability, and corrosion resistance. These round bars are especially ideal for high-temperature service and are utilized in a wide range of demanding applications such as heat treatment, furnaces, oil refining, and chemical processing.
In this blog, we will delve into the features, applications, benefits, and specifications of Stainless Steel 310S Round Bars to help you understand why they are a preferred choice for critical industries.
What is Stainless Steel 310S?
Stainless Steel 310S is a low carbon version of the 310 grade, which offers excellent resistance to oxidation and corrosion, even under mildly cyclic conditions. It contains a high amount of chromium (25%) and nickel (20%), providing superior strength and performance at elevated temperatures.
The "S" in 310S stands for "low carbon," which reduces the risk of sensitization and makes it suitable for applications involving welding and high-temperature exposure.
Key Features of Stainless Steel 310S Round Bars
High Temperature Strength: Retains strength and resists scaling at temperatures up to 1150°C.
Excellent Corrosion Resistance: Performs well in oxidizing and mildly reducing environments.
Good Weldability & Fabrication: Can be easily welded and formed into various shapes and sizes.
Creep Resistance: Maintains mechanical strength at high temperatures.
Low Magnetic Permeability: Non-magnetic in the annealed condition.
