High Temperature:
Austenitic stainless steel with excellent high temperature oxidation resistance Good for continuous exposure to 2100 degree F Intermittent service to 1900 degree F.
Corrosion Resistance:
-
Good aqueous corrosion resistance due to high chromium content
-
Good resistance to oxidizing and carburizing atmospheres
-
Excellent resistance to corrosion at normal temperatures
Heat Resistance:
-
Good resistance to oxidation in intermittent service up to 1040°C temperatures, and in continuous service up to 1150°C.
-
Good resistance to thermal fatigue and cyclic heating.
-
Widely used in areas with elevated temperatures, and sulphur-dioxide gas.
-
Continuous use in 425-860°C temperature range can deteriorate aqueous corrosion resistance due to carbide precipitation.
-
Generally used in applications with temperatures starting from about 800 or 900°C.
Fabrication:
-
Mostly used in heat treatment and process industries in high temperature and corrosive environments
-
Can be easily roller-formed, stamped, and drawn
-
Usually fabricated into complex structures
-
Grade 310 pipes harden after severe forming operations. Hence, it should be followed by annealing
Weldability:
-
Generally weldable by common processes
-
Offers weldability equivalent to 304 and 304L
Applications:
Higher alloyed 310 pipes have excellent strength at elevated temperatures. Along with this, these stainless steel grade pipes offer outstanding resistance to creep deformation and environmental contaminants. Some usage examples of 310 steel include:
-
Oil Burner Parts
-
Heat Exchangers
-
Furnace Parts
-
Welding Filler Wires and Electrodes
-
Combustion Tubes
-
Annealing Covers
-
Fire Box Sheets
