The Quality Of The Stainless Steel 304 Wire Is Related To The Heat Treatment Effect Oct 23, 2017

The surface quality of the Stainless Steel 304 Wire is closely related to the effect of the heat treatment. If the thickness of the surface of the Stainless Steel 304 Wire is not uniform, the thickness of the base metal surface in the thick and thin places is different, and the degree of erosion of the base metal Different, so the Stainless Steel 304 Wire surface will be uneven. Therefore, in the heat treatment processing, the surface must be evenly formed scale.

Attention should be paid to the following situations: Stainless Steel 304 Wire 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 carburized. 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. Operators do not touch the stainless steel parts directly by hand, must be fully degreased in trichlorethylene degreasing agent, Stainless Steel 304 Wire caustic soda solution and then rinse with warm water, and then heat treatment.

If the local part of the treatment before the heat treatment in the residual oxide, heating the remaining parts of the scale and the location of the scale without oxidation, there will be differences in the thickness and composition of the scale, causing pickling after the surface is not uniform, Stainless Steel 304 Wire so Not only to pay attention to the final heat treatment, but also pay full attention to the middle heat treatment and pickling.
