Material Characteristics

• Inconel 600 Sheath
  • High Temperature Resistance: Exhibits excellent high-temperature performance, capable of withstanding low loads below 1,100°C. Its melting temperature ranges from 1,370–1,430°C.
  • Corrosion Resistance: A nickel-chromium-iron-based solid-solution strengthened alloy. The high nickel content provides resistance to many organic and inorganic chemical corrosions, and it is immune to chloride ion stress corrosion cracking. The chromium content offers better corrosion resistance in oxidizing conditions than pure nickel. It can withstand corrosion from chlorine, hydrogen chloride, hydrogen fluoride, etc., making it suitable for thermocouple sheaths in aggressive atmospheres.
  • Fabrication and Welding Performance: Features excellent cold/hot working and welding properties. It can be strengthened through cold working and joined by resistance welding, fusion welding, or brazing.
• SS310 Sheath
  • High Temperature Resistance: An austenitic stainless steel with high chromium and nickel content, offering excellent high-temperature strength and stability. It can withstand temperatures of approximately 1,000–1,200°C.
  • Corrosion Resistance: Demonstrates good resistance to various corrosive media, particularly in oxidizing acid environments. It effectively prevents corrosion and oxidation in high-temperature, corrosive conditions.
  • Fabrication Performance: Easily cold-worked and hot-worked (e.g., rolling, forging, bending) into various shapes and sizes. It also has good weldability and can be joined using common welding methods.

Working Principle

• The mineral insulated thermocouple cable contains two or more thermocouple wires, insulated by magnesium oxide (MgO) powder. When the measuring end senses a temperature change, the thermocouple wires generate a corresponding thermoelectromotive force (EMF). By measuring this EMF, the temperature of the object can be calculated. The Inconel 600 or SS310 sheath protects the thermocouple wires from external factors (e.g., corrosion, mechanical damage, electromagnetic interference), ensuring stable and accurate temperature measurement.
