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 seven-zone mesh belt furnace running at 1120 °C can hold ±3 °C across the belt and still ship parts with inconsistent hardness, because the dew point in the delubrication zone drifted after the belt speed was raised. That is the nature of powder metallurgy: the furnace is not a box that gets hot, it is a chemical reactor with a conveyor attached. The short answer: select a powder metallurgy furnace by the process window it must hold — delubrication profile, atmosphere quality, sintering tempe...
