Stainless Steel Sheet Need To Pay Attention To What The Problem

  Stainless Steel Sheet need to pay attention to what the problem

  Stainless Steel Sheet, for example, in the process of heating its surface with oil, oil cover where the thickness of the oxide and some of the thickness and composition of some of the scale is not the same, and is likely to occur carburizing. Some of the carburized metal under the subcutaneous oxide will be very easily corroded by acid. Heavy oil burner began to burn when the oil droplets, if covered in the workpiece, the workpiece interference is very large. The fingerprints of the hands of the operator will be disturbed if it is contaminated with the workpiece, so the operator can not touch the stainless steel parts directly by hand, to keep the workpiece completely clean.

  If the surface of the workpiece, Stainless Steel Sheet such as lubricating oil attached to cold processing, it is necessary in the trichlorethylene degreasing agent, caustic soda solution fully defatted and then rinse with warm water, and then heat treatment.

  Stainless Steel Sheet on the assumption that the surface of debris, especially organic or gray attached to the workpiece, the heating of course, will have an impact on the scale.

  304 stainless steel furnace furnace air difference in the furnace air in some of the different, the composition of a scale will change, which is composed of pickling after uneven factors. Therefore, in the heating, the furnace parts of the air need to be the same. For this reason, it is also necessary to consider the circulation of air.

  Assuming rich in water, in the heating, the water will transpire, direct contact with some of the water vapor and some other air will be different, the composition of the scale of course, Stainless Steel Sheet is not the same. Thus, objects that are directly touched with the heated workpiece are necessary to be fully dried and used. 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 It is assumed that some of the treatment pieces have residual scale before heat treatment. After heating, there is a place where the scale is left and where there is no scale. There will be a difference in the thickness and composition of the scale, resulting in uneven surface after pickling , So not only pay attention to the heat treatment, but also pay careful attention to the center heat treatment and pickling.

  Gas or oil flame is not in contact with the stainless steel surface or is not in contact with the local occurrence of the scale is not the same. Therefore, Stainless Steel Sheet it is necessary to force the processing device to touch the flame port indirectly when heating.
