310S stainless steel plate

Product Overview

310S stainless steel plate and coil are high-alloy austenitic stainless steel products designed for extreme high-temperature applications. With a high chromium and nickel content, 310S offers excellent oxidation resistance and strength at temperatures up to 1100°C (2012°F). The low carbon content of 310S improves weldability and reduces the risk of carbide precipitation. Available in both plate and coil formats, it is ideal for furnace parts, heat exchangers, and thermal process equipment.

Material Properties

• Outstanding resistance to oxidation and scaling at high temperatures
• High strength and structural stability in thermal cycling conditions
• Good ductility and weldability
• Low carbon content to improve intergranular corrosion resistance
• Non-magnetic in annealed condition

FAQs

Q: What makes 310S suitable for high-temperature environments?

A: The high chromium and nickel content provide exceptional resistance to oxidation and scaling even at temperatures exceeding 1000°C.

Q: Is 310S available in both plate and coil formats?

A: Yes, we provide both formats to meet various project and fabrication requirements.

Q: What kind of coil processing do you offer?

A: We support coil slitting, edge trimming, and coil-to-sheet leveling and cutting services.

Q: Are these materials suitable for welding and bending?

A: Yes, 310S exhibits good weldability and moderate formability. Low carbon content helps reduce welding-related corrosion issues.

Q: How do you package thick plates and heavy coils?

A: We use reinforced steel straps, waterproof wrapping, and wooden/steel pallets to ensure safe shipment.
