  • What Are Cold Rolled finishes?StandardsPost Production Processing to Improve Corrosion ResistanceDifferences Between AlloysCold rolled finishes apply to flat products such as sheet or coil, with thickness less than about 5mm and usually less than 3mm. They are firstly hot rolled into a strip (or cast into a slab which is hot rolled into a strip) and then cold rolled. Cold rolling reduces the thickness by at least 50%. This smooths the surface, refines the grain structure and causes differences in the mechanical properties along and across the rolling direction. In the case of austenitic and duplex alloys, the pro10 Best Outdoor Griddles - (Reviews & Unbiased Guide 2020)Jun 22, 2020 · The griddle plate is made of cold-rolled steel, so some seasoning must be in order before the first cooking session.
