Question 1

What is Stainless Steel 321H Round Bar, and what makes it different from SS 321?

Accepted Answer

Stainless Steel 321H Round Bar is a high-carbon version of SS 321, which is stabilized with titanium to resist intergranular corrosion. The higher carbon content in 321H (compared to 321) improves its strength at elevated temperatures, making it ideal for high-temperature applications in industries such as petrochemicals, aerospace, and heat exchangers.

Question 2

What are the key properties of SS 321H Round Bar?

Accepted Answer

The key properties of SS 321H Round Bar include:

High-temperature strength – Suitable for applications up to 900°C (1652°F).
Excellent corrosion resistance – Especially in oxidizing environments and high-temperature conditions.
Good weldability – Can be welded using standard techniques.
Enhanced creep resistance – Due to higher carbon content, making it better than SS 321 in extreme heat applications.

Question 3

What are the common applications of Stainless Steel 321H Round Bar?

Accepted Answer

SS 321H Round Bar is widely used in industries such as:

Aerospace & Aircraft Industry – Used in exhaust systems and jet engine components.
Chemical Processing – Ideal for heat exchangers and pressure vessels.
Power Generation – Used in boiler tubes and superheaters.
Oil & Gas Industry – Suitable for refinery equipment and pipelines.
