310/310H stainless steel 8*1.5mm coiled/capillary tube for heat exchanger
Sihe Stainless inventory now includes 310H Plate and Processed Flat Bar (Alloy 310H UNS S31009), ideally suited for high-temperature applications such as heat treatment and chemical processing equipment. Alloy 310H (UNS S31009) has a carbon content restricted to exclude the lower end of the 310 range. This makes 310H the grade of choice for high temperature applications. This steel has good resistance to oxidation at temperatures of up to 1040°C (1904°F) in intermittent service and 1150°C (2102°F) in continuous service; however it is recommended that this steel should not be continuously used at 425-860°C (797-1580°F) range due to carbide precipitation.

310/310H stainless steel 8*1.5mm coiled/capillary tube for heat exchanger
Applications
It is widely used in environments where sulfur dioxide gas is present at high temperatures, heat treatment industry, and the chemical process industry.
Corrosion Resistance:
. The high chromium content – intended to increase high temperature properties – also gives this grades good aqueous corrosion resistance.
. In high temperature service, 310H exhibits good resistance to oxidising and carburising atmospheres.
