Can SS 310 operate at 400°C without problems？
Leave a message
If you are selecting SS 310 stainless steel for equipment operating around 400°C (752°F), the short answer is yes. SS 310 is an austenitic heat-resistant stainless steel with high chromium and nickel contents, and 400°C is well below the temperature range where its high-temperature oxidation resistance becomes a major design limitation.
However, "can SS 310 operate at 400°C?" should not be answered by temperature alone. Service life also depends on continuous or cyclic operation, applied stress, atmosphere, corrosion conditions, wall thickness, welding, and required mechanical strength.
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.
If possible, please provide the following information: Is the component subjected to continuous mechanical loads or pressure?
What are the specific chemical conditions (e.g., gases, moisture, or chemical substances involved)?
This will allow me to determine whether the standard Type 310 or the low-carbon Type 310S is better suited to your specific application.

FAQ
Is SS 310 superior to 316 at high temperatures?
Not in every application. 316 is valued primarily for its resistance to aqueous corrosion (especially in chloride environments), whereas 310 is optimized for heat and oxidation resistance. The choice of material depends on the specific process environment.
Can SS 310 be used for furnace equipment?
Yes. Furnace equipment is a typical application for 310/310S. Outokumpu lists furnace equipment, heat treatment baskets, heat exchangers, steam boilers, and thermowells as typical applications.
Will SS 310 rust at 400°C?
While SS 310 offers excellent oxidation resistance compared to many standard stainless steels, stating that it "never rusts" would be an overstatement. High-temperature corrosion behavior depends on the atmosphere, contaminants, and thermal cycling conditions.
