310 310S stainless steel sheet 2B finish 1219mm width mill finish
Description:
Alloy 310 is an austenitic stainless steel that combines excellent high temperature properties with good ductility and weldability. It is typically used for elevated temperature applications as its high chromium and nickel content provide solid corrosion resistance, excellent resistance to oxidation, and superior strength. Due to its high chromium and nickel content, it is superior to 304 or 309 stainless in most environments.
Haosteel stainless 310 sheet and processed flat bar provides superior resistance to corrosion and heat exposure, in even the most demanding environments.

Corrosion resistance:
Provides excellent corrosion resistance
High chromium content allows for good aqueous corrosion resistance
Excellent resistance at normal temperatures and also has good resistance to oxidizing and carburizing atmospheres
Heat resistance:
Good resistance to oxidation in intermittent service in air at temperatures up to 1040°C and 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 425-860°C range not recommended due to carbide precipitation, if subsequent aqueous corrosion resistance is needed
Generally used at temperatures starting from about 800 or 900°C – above the temperatures at which 304H and 321 are effective.
Fabrication:
Commonly used in the heat treatment and process industries due to high temperature and corrosive environments
Often fabricated into complex structures
Roller-forms, stamps and draws readily
Because 310 work hardens, severe forming operations should be followed by an anneal
Weldability:
Austenitic stainless steel is generally considered to be weldable
Generally considered to have weldability equivalent to 304 and 304L
Applications:
The higher alloyed stainless steels generally have excellent strength at elevated temperatures along with outstanding resistance to creep deformation and environmental attack. Therefore, Alloy 310 is used widely in industries such as heat treatment and chemical processing. Some examples include:
Furnace Parts
Oil Burner Parts
Heat Exchangers
Welding Filler Wire and Electrodes
Annealing Covers
Combustion Tubes
Fire Box Sheets
