309S Cold Rolled Stainless Steel Strip For Electric Heating Tube

Performance advantages
• High temperature stability: When working at 800-900℃ for a long time, the shell has no obvious deformation and oxidation peeling. It is suitable for replacing metal electric heating tubes that are not resistant to high temperatures (such as carbon steel, 304 stainless steel), and is used in high-temperature heating furnaces, molten metal heating and other scenarios.
• Corrosion resistance adaptation: It has certain corrosion resistance to high-temperature flue gas and weakly corrosive gases (such as industrial waste gas heating), which is better than ordinary heat-resistant steel, but not suitable for strong acid and alkali environments (310S or titanium alloy must be selected).
• Long life: The oxidation resistance loss is slow at high temperature, and the mechanical properties are stable. The service life is usually 2-3 times that of 304 electric heating tubes (under high temperature conditions).

Application scenarios
• Industrial heating: such as heating elements in high-temperature ovens, heat treatment furnaces, and sintering furnaces, replacing traditional resistance wires, improving heating efficiency and equipment durability.
• Metallurgy and chemical industry: used for heat preservation heating tubes for molten metals (such as aluminum and zinc), or auxiliary heating of high-temperature chemical reactors, and can withstand high temperature and slight corrosion of materials.
• Environmental protection equipment: In waste incineration tail gas treatment and high-temperature exhaust gas heating devices, it is used as a heating component to adapt to the high-temperature environment of flue gas.

In summary, 309S stainless steel electric heating tubes are an ideal choice for high-temperature industrial heating scenarios due to their super high temperature resistance and oxidation resistance. The core advantage lies in stability and long life under extreme temperatures.
