Can SS 310 operate at 400 degrees C without problems？

SS 310 stainless steel is a high-alloy austenitic stainless steel designed for high-temperature applications, widely used in industries like furnaces, heat exchangers, petrochemical equipment, and power generation. If you are looking for a reliable supplier of SS 310 stainless steel with stable supply, competitive pricing, and certified quality, GNEE offers a full range of SS 310 sheets, plates, bars, and tubes suitable for continuous operation at temperatures up to 1150°C.

 

Can SS 310 operate at 400 degrees C without problems?

Yes, SS 310 stainless steel can operate normally at temperatures up to 400°C (752°F). It is designed for high-temperature applications and can withstand continuous use up to 1150°C (2100°F), exhibiting excellent resistance to oxidation and corrosion. While 400°C is well within the operating temperature range of SS 310, prolonged exposure to a specific temperature range of 590°C to 870°C can lead to the formation of the σ phase, making the steel brittle. However, temperatures below 400°C do not pose a problem for SS 310.

Can SS 310 resist oxidation at 400°C?
Yes, SS 310 is specifically alloyed with 25% Cr and 20% Ni, providing excellent oxidation resistance up to 1150°C. At 400°C, oxidation is negligible, making it safe for long-term operation.

 

 Is SS 310 better than SS 304 at 400°C?
Yes. While SS 304 is suitable up to 870°C intermittently, SS 310 offers higher creep and oxidation resistance, making it more reliable for continuous high-temperature exposure.

  

SS 310 price list

Due to high demand for high-temperature resistant stainless steel, SS 310 pricing has shown steady growth. Current market trends indicate:

Sheet / Plate: $5.5–$7.0 per kg (depending on thickness and finish)

Seamless Tube / Pipe: $8.0–$10.0 per kg

Round Bar / Rod: $6.0–$8.5 per kg

Urgency Note: Global steel supply constraints and rising energy costs make SS 310 procurement competitive. Early orders help ensure timely delivery.
