Stainless Steel Sheet Should Pay Attention To The Problem

  Stainless Steel Sheet should pay attention to the problem

  Stainless Steel Sheet If the surface of the workpiece is attached with oil, the thickness of the scale of the oil attachment and the thickness and composition of the other parts are different and carburizing. The carburized part of the base metal will be severely attacked by acid. Heavy oil burner when the initial combustion of oil droplets, if attached to the workpiece, the impact is also great. The operation of the fingerprints attached to the workpiece will also be affected. Therefore, the bath for the major members do not touch the stainless steel hand, do not make the workpiece stained with new oil. Must wear clean gloves.

  If the surface of the workpiece if the cold processing of lubricating oil, etc., must be in the trichlorethylene degreasing agent, caustic soda solution fully defatted and then rinse with warm water, and then heat treatment.

  Stainless Steel Sheet If the surface of debris, especially organic matter or ash attached to the workpiece, the heating of course, will have an impact on the scale.

  304 stainless steel furnace furnace atmosphere difference in the furnace atmosphere in the local differences, the formation of a scale will change, which is caused by acidity after the reasons for uneven. Therefore, in the heating, the furnace parts of the atmosphere must be the same. To this end, we must also consider the cycle of the atmosphere.

  In addition, it is necessary to evaporate the moisture, and the parts of the direct contact with the water vapor are different from those of the other parts, and the formation of the scale is, of course, It is different. Therefore, objects that are in direct contact with the heated workpiece must be fully dried to use. However, after drying, such as placed at room temperature, in the case of high humidity, the water will still condense on the surface of the workpiece. So, it is best to dry before use.

  Stainless Steel Sheet If the local part of the treatment piece has residual oxide before heat treatment, there will be a fraction of the scale and composition of the scale on the remaining parts of the scale and the site where there is no scale. After the pickling, the surface is uneven , So not only pay attention to the final heat treatment, but also pay full attention to the middle heat treatment and pickling.

  Oxygen or oil flames in direct contact with the stainless steel surface and the place where the contact does not produce the difference. Therefore, it is necessary to make the treatment member not directly in contact with the flame port during heating.
