Several problems should be paid attention to in surface treatment of quality Stainless steel profile
The surface quality of quality Stainless steel profile mainly depends on the pickling process after heat treatment. If the surface oxide scale formed by the previous heat treatment process is thick or the structure is uneven, pickling cannot improve the surface finish and uniformity. Therefore, sufficient attention should be paid to the heating of the heat treatment or the surface cleaning before the heat treatment.
If the thickness of the oxide scale on the surface of the quality Stainless steel profile is not uniform, the surface finish of the base material at the thickness is also different. Evenly. Therefore, the oxide scale must be uniformly formed during the heat treatment and heating process. In order to meet this requirement, we must pay attention to the following issues: If oil adheres to the surface of the workpiece during the heating process, the thickness of the oxide scale of the oil-attached part is different from that of other parts, and carburization will occur. The carburized part of the oxidized base metal will be severely corroded by acid. The operator's fingerprint is also affected when it is attached to the workpiece. Therefore, the operator shall not directly touch the stainless steel material with his hands, and shall not stain the work piece with new oil. Clean gloves must be worn during operation.
If lubricating oil is attached to the surface of the workpiece during cold working, it must be fully degreased in trichloroethylene pupa degreaser and caustic soda solution, then washed with warm water, and then heat treated. If there are impurities on the surface, especially organic matter or ash attached to the workpiece, heating will inevitably affect the oxide scale.
In addition, there are many details in the quality inspection process that require the operator's attention. Therefore, the operator's own technical quality has become the key to ensuring the quality of products such as the quality stainless steel profile.
