Technical Data

Sheath Material of SS310
Applications: Nuclear power plants, crude oil and petrochemistry, furnace construction, heat exchangers, air heaters, cement and brick kilns, glass works, jet engine afterburner and gas inlet temperature measuring applications.
Max. continuous temperature: 1150°C
Heat resistance: Good resistance to oxidation in intermittent service in air at temperatures up to 1150°C in continuous service. Good resistance to thermal fatigue and cyclic heating. Widely used where sulphur dioxide gas is encountered at elevated temperatures. Continuous use in 425 to 850°C range not recommended but often performs well in temperatures above and below this range.
Corrosion resistance: Excellent resistance at normal temperatures and when in high temperature service exhibits good resistance to oxidation and carburizing atmospheres up to 900 °C. Resists fuming nitric acid at room temperature and fused nitrates up to 420°C.
Welding: Good characteristics suited to all standard welding methods.
