FAQ's of SS 321 Flanges:

Q: How are SS 321 Flanges different from SS 304 or 316 Flanges?

A: SS 321 Flanges offer enhanced resistance to intergranular corrosion at high temperatures due to titanium stabilization, making them ideal for high-heat applications compared to the more general-use SS 304 or 316.

Q: What industries commonly use SS 321 Flanges?

A: These flanges are used extensively in petrochemical, oil & gas, chemical, and power plant industries thanks to their robustness, corrosion resistance, and ability to withstand high temperatures.

Q: When is it recommended to use SS 321H Grade Flanges?

A: SS 321H Grade Flanges are recommended when higher strength at elevated temperatures is needed-particularly above 500C-making them suitable for heat exchangers, boilers, and superheater tubes.

Q: Where are SS 321 Flanges manufactured and supplied from?

A: Our SS 321 Flanges are manufactured, exported, and supplied from India, leveraging advanced forging and machining processes to meet global customer requirements.
