MIM stainless steel plates are attached to the surface and, when exposed to cold oils, must be skimmed completely, then washed with warm water and degreaser trichloroethylene, caustic soda solution, and then heat-treated. If there is a stainless steel chip on the surface, especially if the organism or gray is attached to the workpiece, the heating will definitely have an impact scale.

Differential MIM stainless steel furnace atmosphere the furnace atmosphere varies from place to place and the scale will form a variation due to uneven pickling. Therefore, during heating, the atmosphere in each part of the furnace must be the same. To do this, we also need to consider the cyclical atmosphere.

If the local members of MIM stainless steel have residual oxides before the heat treatment process, and the oxide heats the remaining parts without scaling, the scale thickness and composition of the oxide skin are different, the surface will not cause the acid uniformity, so pay attention to the final heat treatment, but also pay full attention to the middle annealing and pickling.

In addition, through the composition of heating workpieces such as gantry bricks, asbestos, etc., if there is water, when heated, the water will evaporate, and the parts in direct contact with other parts of the vapor atmosphere will be different, of course, the formation of scale is different. Therefore, the object and the workpiece heating direct contact, before use must be completely dry. However, after drying at room temperature under high humidity conditions, water still condenses on the surface of the workpiece. Therefore, it is best to dry before use.
