Frequently Asked Questions

What is the temperature limit of Stainless Steel 310 Flanges?

Stainless Steel 310 Flanges can withstand up to 1040°C (1900°F) in continuous service and up to 1100°C (2010°F) in intermittent service, subject to loading conditions and atmospheric composition.

Is Stainless Steel 310 better than 304 for high-temperature applications?

Yes, SS 310 offers significantly better heat and oxidation resistance than SS 304, making it more suitable for elevated-temperature environments.

What is the difference between 310 and 310S stainless steel flanges?

SS 310S is the low-carbon version of SS 310, providing improved weldability and reduced carbide precipitation during welding.

Why is Stainless Steel 310 used in furnace applications?

SS 310 is used in furnace applications because it maintains its strength and resists oxidation at very high temperatures.

Can SS 310 Flanges handle continuous high heat exposure?

Yes, SS 310 Flanges are specifically designed for continuous high-temperature service and perform reliably in heat-intensive applications.
