What is the Tube Furnace Tube Made Of? An In-Depth Analysis

Table of Contents

When it comes to selecting a tube furnace, the material of the furnace tube plays a crucial role in its performance and suitability for different applications.

ZYLAB is a leading scientific instrument supplier, offering furnace tubes and tube furnaces made from materials such as quartz, alumina, and stainless steel, designed for various experimental research applications.

Types of Tube Furnace Tubes

1. Quartz Tube

Characteristics:

  • Made from high-purity silica, quartz tubes are highly resistant to thermal shock and can operate at temperatures up to 1200°C.
  • Quartz is transparent, allowing for direct observation of the processes inside the tube.

3. Stainless Steel Tube

Characteristics:

  • Stainless steel tubes, particularly 310S and 316L grades, combine strength with corrosion resistance.
  • 310S stainless steel is designed for high-temperature environments (up to 1150°C), while 316L, with added molybdenum, excels in corrosion resistance and operates effectively at 1200–1300°C.

Advantages:

  • High mechanical strength and resistance to deformation under high pressure.
  • Versatile for vacuum, controlled atmospheres, and corrosive conditions.
  • ZYLAB’s high-temperature high-pressure furnace tubes exhibit creep properties, releasing gas safely without risk of brittle failure.

Applications:

  • Ideal for processes involving vacuum conditions, reactive gases, or high-pressure environments.
  • Suitable for sintering, melting, and thermal analysis in research and industrial settings.
