SUS310 310S stainless steel plate 1500mm width 3 - 20mm thickness
Description:
Grade 310 (UNS S31000) and its various sub- grades combine excellent high temperature properties with good ductility and weldability.
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 temperature applications.
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.
Corrosion Resistance
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.
Specified Properties
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.

Comparison:
310 is subject to stress corrosion cracking but more resistant than Grades 304 or 316. Consult hao Technical Assistance for specific environmental recommendations.
Welding
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.
"Dual Certification"
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.
Typical Applications
Furnace parts. Oil burner parts. Carburising boxes. Heat Treatment baskets and jigs. Heat exchangers. Welding filler wire and electrodes.
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:
Furnace Parts
Oil Burner Parts

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.
Comparison:
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 corrosion.
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.
