310s Stainless Tube Shields
Stainless 310s tube shields are made of 310s stainless steel and can be customized to fit perfectly straight sections, curved sections and even fins and specialty tubes.
Stainless Steel Grade 310 is a medium carbon austenitic stainless steel, for high temperature applications such as furnace and heat treatment equipment.
310S stainless steel plates offer a combination of high-temperature resistance, corrosion resistance, and mechanical strength, making them an ideal choice for demanding applications in industries such as power generation, oil and gas, and chemical processing. For projects requiring a material that can endure extreme temperatures while maintaining structural integrity, 310S stainless steel is a top-tier option.
310S stainless steel sheets is similar to stainless steel 310 apart from a lower content of carbon that reduces carbideprecipitation and enhances weldability. The soaring nickel and chromium contents of ss 310s plates offer similar corrosionresistance, higher resistance to oxidation and the holding of a superior portion of room temp potency than the usual austeniticsteel such as S304.
AISI 310S stainless steel is a high-temperature resistant austenitic stainless steel with excellent mechanical properties, oxidation resistance, and heat resistance due to its high chromium and nickel content. It is known for its superior corrosion resistance, especially in comparison to the common austenitic alloys like Type 304, and retains a larger fraction of room temperature strength.

Alloy 310 can be easily welded and processed by standard shop fabrication practices.
The 310S grade is particularly chosen for applications that involve moist corrodents at temperatures lower than what is typically considered "high temperature" service due to its lower carbon content compared to the standard 310 grade. This makes 310S less prone to embrittlement and sensitization in service.
For high-temperature applications, 310H, a variant with a higher carbon content, is preferred for its better creep strength. However, 310H may be prone to sigma phase embrittlement in the temperature range of 650–900°C.
When it comes to corrosion resistance, while 310S has good aqueous corrosion resistance, it lacks molybdenum, making it less resistant to pitting than grades like 316. It is also susceptible to sensitization and intergranular corrosion after exposure to elevated temperatures or welding.
The 310S stainless steel is available in various forms such as plate, sheet, strip, bar, rod, tube, pipe, and wire, and can be supplied with different surface finishes. It is also commonly produced in "Dual Certified" form, mainly in plate and pipe, which means it meets the specifications for both 310H and 310S.
It is used in various industrial applications such as furnace parts, heat treatment equipment, heat exchangers, and in environments where it may be exposed to high temperatures and corrosive conditions.
Applications for these grades of stainless steel plate include the manufacture of cryogenic components and use in furnaces, particularly in the construction of burners, recuperators, doors, fans and pipework. As these grades of stainless steel can withstand very high temperatures, they are also commonly used in the food processing, chemical and pharmaceutical industries. They are also used in fluidised bed furnaces, coal burners, grilles, pipework and air ducts. Ore and steel processing plants also utilise the unique properties of this stainless steel plate in smelting, steel melting and continuous casting equipment. These grades are also widely used in the petroleum refining industry, particularly in catalytic recovery systems, flares, recuperators and pipe hangers. This grade is used in power generation applications; it is used in coal gasifier internals, pulverised coal burners and tube hangers. Sintering and cement plants also utilise the properties of this stainless steel plate in burners and burner shields, feed and discharge systems and wind boxes. Another industry where these grades of stainless steel are widely used is in the thermal processing industry. It can be found in annealing covers and boxes, burner grates, doors, fans, mufflers, retorts and walking beams. These grades of stainless steel plate can withstand very high temperatures, making them useful in a wide range of industries.
310S stainless steel plates are used in a variety of high-demand applications across different industries:
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
