What temperature can the pencil heater withstand?

Pencil heater is particularly widely used in machinery and equipment with molds in various industries because of its high thermal efficiency and easy installation. At the same time, there are inner leads and outer wires in the structure, which can largely meet the needs of users. However, many users complained that the pencil heaters purchased from other manufacturers could not stand the temperature and burn out easily. So I want to know what temperature our company's pencil heater can withstand?

  Before customers order pencil heaters, they will ask customers for their working temperature. We choose different heating tube materials based on the customer's working temperature. Here is a list for everyone:

1. If the working temperature of the pencil heater is around 100-300 degrees, the material should be stainless steel 304.

2. If the working temperature of the pencil heater is around 400-500 degrees, stainless steel 321 can be used.

3. If the working temperature of the pencil heater is around 600-700 degrees, the tube material should be stainless steel 310S.

      Therefore, based on the list of commonly used temperature and material relationships for pencil heaters above, I believe everyone should know that the temperature that the pencil heater can withstand depends on the material selected.
