In essence, cold-rolled steel is hot-rolled steel that has undergone additional processing. In cold reduction mills, the steel is treated further after being cooled and then subjected to annealing and/or tempers rolling. Steel produced using this method will have tighter dimensional tolerances. Also, it has a larger selection of surface treatments. These sheets are made available by various stainless steel cd overlay sheets manufacturer. While the name of the product truly refers to the rolling of the flat rolled sheets, the phrase “Cold Rolled” is incorrectly applied to all products.
Processing of Stainless Steel CD Overlay Sheets
The phrase “cold finishing” is used to describe the process of cold drawing and/or turning, grinding, and polishing bar items. This method yields higher yield points and has four primary benefits:
- Cold drawing improves yield and tensile strengths, frequently obviating the need for additional expensive thermal treatments.
- The surface finish is improved by polishing.
- Surface flaws disappear while turning.
- The initial size tolerance range is reduced through grinding.
When compared to hot rolled products, all cold products have a greater surface polish and are superior in terms of tolerance, concentricity, and straightness. Due to the higher carbon content, cold finished bars are often more difficult to deal with than hot rolled ones. Considering cold rolled and hot rolled sheets, this can’t be said, though. In this case, the cold-rolled product is softer than the hot-rolled sheet because it is normally annealed and has a low carbon content.
Benefits of SS CD Overlay Sheets
Cold-rolled steels are often stronger and harder than normal hot-rolled steels in terms of physical properties. As the metal is formed at lower temperatures, work hardening increases the steel’s hardness, resistance to tension breaking, and resistance to deformation. However, the material may also experience internal stress as a result of these extra treatments. If the steel is not stress alleviated before cutting, grinding, or welding, this may result in unanticipated warping.
Uses of Stainless Steel CD Overlay Sheets
Any project where the main considerations are tolerances, good surface finish, roundness, and orientation.
