FAQ's
Stainless Steel 310/310S Flanges are high-temperature
stainless steel flanges manufactured from austenitic chromium-nickel
stainless steel. They offer excellent oxidation resistance, good
mechanical strength at elevated temperatures, and resistance to
carburization and thermal cycling.
The primary difference is carbon content.
SS 310S has a lower carbon content than SS 310,
which improves its resistance to sensitization during welding and
makes 310S particularly suitable for welded high-temperature applications.
Stainless Steel 310/310S Flanges are commonly manufactured according
to standards such as ASME B16.5, ASME B16.47, ASTM A182,
and related specifications, depending on flange type, size,
pressure class, and application requirements.
SS 310/310S Flanges are commonly used in
furnaces, heat exchangers, petrochemical plants,
refineries, power generation equipment, heat-treatment equipment,
and high-temperature process piping where resistance to
heat and oxidation is required.
Key advantages include
excellent high-temperature performance, strong oxidation
resistance, good corrosion resistance, resistance to carburization,
and good mechanical properties at elevated temperatures.
SS 310S also offers improved weldability for high-temperature
fabricated systems.
