What is Stainless Steel 310?
SS 310 usually refers to a specific type of stainless steel called AISI 310 or UNS S31000. It is a high-temperature austenitic stainless steel that is often used in applications that involve elevated temperatures. It is widely used in furnaces, heat exchangers, and other high-temperature industrial equipment.
AISI 310 stainless steel is known for its excellent oxidation resistance in high-temperature environments. This stainless steel alloy can withstand temperatures up to 1100°C in continuous service and up to 1150°C in intermittent service. This makes it suitable for applications that require resistance to heat and thermal cycling.
Here are some key characteristics of SS310:
1. High-Temperature Resistance
It retains its strength and resistance to oxidation even at elevated temperatures.
2. Corrosion Resistance
It offers good resistance to corrosion in various atmospheres, including oxidizing and reducing environments.
3. Austenitic Structure
SS310 is a stainless steel alloy that has an austenitic crystal structure. This provides excellent formability and weldability.
4. Scaling Resistance
SS 310 has good resistance to scaling and spalling in cyclically heated applications.
5. High Strength
SS 310 retains its mechanical properties at high temperatures, making it suitable for structural components in high-temperature environments.
