SUS310 310S stainless steel plate 1500mm width 3 - 20mm thickness
Grade 310 (UNS S31000) and its various sub- grades combine
excellent high temperature properties with good ductility and
Grade 310H (UNS S31009) has a carbon content restricted to exclude
the lower end of the 310 range, so is the grade of choice for high
Grade 310S (UNS S31008) is used when the application environment
involves moist corrodents in a temperature range lower than that
which is normally considered "high temperature" service. The lower
carbon content of 310S does reduce its high temperature strength
compared to 310H.
Grade 310L is a series of proprietary grades, generally with a
0.03% maximum carbon and sometimes used for very specific corrosive
environments such as urea production.
Like other austenitic grades the 310 family have excellent
toughness, even down to cryogenic temperatures, although other
grades are normally used in sub-zero environments.
The high chromium content - intended to increase high temperature
properties - also gives these grades good aqueous corrosion
resistance. The PRE is approximately 25, and sea water resistance
about 22°C, similar to that of Grade 316. In high temperature
service they exhibit good resistance to oxidising and carburising
atmospheres. Resist fuming nitric acid at room temperature and
fused nitrates up to 425°C.
The high carbon contents of all except 310L do make these grades
susceptible to sensitisation and hence intergranular corrosion
after elevated temperature exposure or welding.
These properties are specified for flat rolled product (310S
stainless steel plate, sheet and coil) in ASTM A240/A240M (310S and
310H) and ASTM A167 (310). Similar but not necessarily identical
properties are specified for other products such as pipe and bar in
their respective specifications.

310 is subject to stress corrosion cracking but more resistant than
Grades 304 or 316. Consult hao Technical Assistance for specific
Good characteristics suited to all standard methods. Grade 310S
electrodes generally recommended for fusion welding. AS 1554.6
pre-qualifies welding of 310 with Grade 310 rods or electrodes.
310H and 310S are often produced in "Dual Certified" form – mainly
in plate and pipe. These items have chemical and mechanical
properties complying with both 310H and 310S specifications.
Product complying with 310 only or dual certified 310 and 310S may
have a carbon content below 0.04% which will not be acceptable for
some high temperature applications.

The higher alloyed stainless steel generally have excellent
strength at elevated temperatures along with outstanding resistance
to creep deformation and environmental attack. Therefore, Alloy 310
stainless steel is used widely in industries such as heat treatment
and chemical processing. Some examples include:
Oil Burner Parts
Welding Filler Wire and Electrodes
Fire Box Sheets
Automotive purification equipment
The 310S stainless steel plate is a high-alloy stainless steel of
the 25Cr-20Ni system. It has excellent high-temperature oxidation
resistance and is suitable for making various furnace components.
The maximum temperature is 1200°C and the continuous use temperature is 1150°C.
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
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.
310S stainless steel is austenitic chrome-nickel stainless steel
with good oxidation resistance and corrosion resistance. Because of
the high percentage of chromium and nickel, it has much better
creep strength, can work continuously at high temperature, and has
good resistance. High temperature. Due to high nickel (Ni) and
chromium (Cr) content, it has good resistance to oxidation and
310S stainless steel plate
Acid and alkali resistance, high temperature resistance, high
temperature resistant steel pipe is specially used for the
manufacture of electric heating furnace tubes, etc. After adding
carbon content in austenitic stainless steel, the strength is
improved due to its solid solution strengthening, and the chemistry
of austenitic stainless steel The composition characteristics are
elements such as molybdenum, tungsten, niobium and titanium added
on the basis of chromium and nickel. Since the structure is a
face-centered cubic structure, it has high strength and creep
strength at high temperatures.
