Stainless steel wire surface quality and heat treatment of the relationship between __ wire mesh products co. , LTD

Heat treatment can improve the quality of products, stainless steel wire surface quality, mainly depends on the heat treatment after pickling process, this article about the relationship between the stainless steel wire appearance quality and heat treatment. If the appearance of stainless steel wire scale thickness is uneven, the thick and thin places below the substrate metal surface finish is different also, dissolve and pickling of oxide skin appearance and scale attached to parts of the matrix metal by acid corrosion degree are different. So, stainless steel wire is uneven. During heat treatment heating, therefore, it is necessary to make it evenly to form scale, to arrive at one to involve the following conditions, and to take note: if the heating workpiece surface attachment, oil scale thickness of attached parts and other parts of the oxide coating thickness and composition are different, and carburizing will happen. Subcutaneous matrix metal oxide were part of carburizing will seriously by the acid corrosion. The initial burning of heavy oil burner jet of oil droplets, if attached to the workpiece, the influence is very big also. Operating official's fingerprint adhesion when also can have influence on the artifact. So don't directly with the hand touch operation official stainless steel pieces, don't make the work-piece with new oil looks like have cold work attachment of lubricating oil and so on, it is necessary to the trichloroethylene full degreasing degreasing agent, caustic soda solution and then wash with warm water, then heat treatment. If artifacts appearance have sundry, especially organic matter or ash attached workpieces, heating, of course, will have an impact on the scale. Direct contact of oil or gas flame stainless steel appearance and no contact with the local there are differences in the scale of what has happened. So it necessary to make the heat treatment unit not direct contact with the flame.
