Stainless Steel Vacuum Annealing Furnace
This equipment is a horizontal structure with a square structure in the middle of a circle, which can ensure high vacuum efficiency while also making the furnace resistant to deformation and durable. The furnace is made of 310S stainless steel, which has good temperature resistance and strong pressure bearing capacity. The outer layer is carbon steel, and the two layers are cooled by circulating water, which has a long service life. It is mainly used for vacuum annealing of special materials, stainless steel, selenium steel sheet core, precious metal parts, silver-copper composite rivets and sheet parts.

A vacuum furnace is a high-tech industrial oven used for heat treatment processes, primarily in the manufacturing and processing of metals, ceramics, and other materials. The furnace operates in a controlled vacuum environment, meaning that the air is removed from the chamber, creating a low-pressure atmosphere. This unique condition allows for specific and often superior material properties to be achieved during the heating process. Let’s dive deeper into the purpose of a vacuum furnace and why...
