01 What are the key benefits of using Stainless Steel 321 pipe fittings?

Stainless Steel 321 provides excellent corrosion resistance, especially in intergranular environments, making it suitable for applications involving welding and exposure to elevated temperatures.

02 What is the maximum service temperature for SS 321 fittings?

Stainless Steel 321 can withstand temperatures up to 800°C (1472°F), making it well-suited for applications in high-temperature environments.

03 In which industries are Stainless Steel 321 fittings widely used?

Stainless Steel 321 fittings used in industries such as petrochemical, chemical processing, and aerospace, where corrosion resistance and high-temperature stability are crucial.

04 What is the primary difference between Stainless Steel 321 and 321H fittings?

The main distinction lies in the carbon content. Stainless Steel 321H has a higher carbon content compared to 321, which enhances its high-temperature strength.
