What is the Relationship Between the Surface Quality of Fine Stainless Steel Wire Mesh and Heat Treatment?
As a Stainless Steel Wire Mesh Supplier, share with you. Heat treatment can improve the quality of products. The appearance quality of stainless steel wire mesh is mainly determined by the pickling process after heat treatment. This article will talk about the relationship between the appearance quality of stainless steel wire mesh and heat treatment. If the thickness of the outer oxide scale of the stainless steel wire mesh is not uniform, the surface finish of the base metal under the thick and thin areas is also different, and the dissolution of the outer oxide scale during pickling and the degree of corrosion of the base metal at the attachment position of the oxide scale by acid different.To get more news about Stainless Steel Crimped Wire Mesh Tray, you can visit resenwiremesh.com official website.
Therefore, the appearance of the stainless steel wire mesh is uneven. Therefore, during heat treatment, it is necessary to form oxide scale uniformly. To achieve one, the following conditions must be paid attention to: It is assumed that oil adheres to the surface of the workpiece during heating, the thickness of the oxide scale at the oil adhered part and the oxidation of other parts The thickness and composition of the skin are different, and carburization occurs. The carburized part of the base metal under the oxide skin will be severely corroded by acid.
The oil droplets sprayed out by the heavy oil burner when it first burns will have a great impact if it adheres to the workpiece. The fingerprint of the operator may also be affected when it is attached to the workpiece. Therefore, operators should not directly touch the stainless steel parts with their hands, and do not stain the workpiece with new oil. If there is lubricating oil attached to the surface of the workpiece during cold processing, it is necessary to degrease adequately in trichloroethylene degreaser and caustic soda solution before using it. Wash with warm water, and then heat treatment.
Assuming that there are impurities on the surface of the workpiece, especially when organic matter or ash adheres to the workpiece, heating will certainly affect the oxide scale. There is a difference between the surface of stainless steel that is in direct contact with the flame of gas or oil and the oxide scale produced in the area that is not in contact. Therefore, it is necessary to prevent the treatment part from directly contacting the flame port during heating. If the part of the processed part has residual oxide scale before heat treatment.
After heating, there will be a difference in the thickness and composition of the oxide scale in the area where there are residual oxide scale and the area without oxide scale, which will cause uneven appearance after pickling, so pay attention to not only the final heat treatment, but also the intermediate heat treatment. And pickling. The effect of different appearance finishes.
If the surface finish of the stainless steel wire mesh is different, even if it is heated the same, the scale on the rough and fine surface will be different. For example, in the area where some defects have been sorted and not sorted, the conditions of the oxide scale are different, which causes uneven appearance of the workpiece after pickling.
